"Is Low Blood Pressure Holding You Back? Understanding Hypotension"

 

*Introduction -

Blood pressure is the force that blood exerts against the walls of your arteries as it circulates through your body. It’s measured in millimeters of mercury (mmHg) and recorded as two numbers: systolic pressure (the pressure when your heart beats) over diastolic pressure (the pressure when your heart rests between beats). A typical “normal” blood pressure reading is around 120/80 mmHg. While high blood pressure, or hypertension, often grabs the spotlight, low blood pressure—known as hypotension—can also have significant health implications.

Hypotension is generally defined as a blood pressure reading below 90/60 mmHg. For some people, low blood pressure is normal and causes no problems. However, when it leads to insufficient blood flow to organs like the brain, heart, and kidneys, it can become a concern. Hypotension might signal an underlying condition, such as dehydration or heart disease, or it can occur as a standalone issue. In severe cases, it can even lead to shock—a life-threatening state where the body’s organs don’t get enough oxygen.

This article provides an in-depth look at hypotension, exploring its types, causes, symptoms, how it’s diagnosed, treatment options, and ways to prevent it. Whether you’re someone with naturally low blood pressure or you’re experiencing troubling symptoms, understanding this condition is key to managing it effectively.

Types of Hypotension

Hypotension isn’t a one-size-fits-all condition—it comes in several forms, each with distinct triggers:

• Orthostatic Hypotension: This happens when your blood pressure drops suddenly after standing up from sitting or lying down. It’s common in older adults and can increase the risk of falls.
• Postprandial Hypotension: A drop in blood pressure after eating, often due to blood being redirected to the digestive system. It’s more frequent in the elderly or those with nervous system disorders.
• Neurally Mediated Hypotension (NMH): Caused by a miscommunication between the heart and brain, often triggered by standing for long periods. It’s more common in younger people and can lead to fainting.
• Severe Hypotension: A critical condition often linked to extreme causes like massive blood loss, severe infections, or allergic reactions. It requires urgent medical care.

Identifying the type of hypotension helps guide treatment and management strategies.

Causes of Hypotension

Low blood pressure can stem from a wide range of factors. Here’s a detailed look at the most common causes:

• Dehydration: Losing more water than you take in—through sweating, vomiting, diarrhea, or not drinking enough—reduces blood volume, lowering blood pressure. Imagine a hiker in the scorching sun who hasn’t refilled their water bottle; they might feel dizzy as their blood pressure dips.
• Heart Problems: If the heart can’t pump blood effectively, blood pressure drops. Conditions like bradycardia (a slow heart rate), heart valve issues, or heart failure can all contribute. For example, in heart failure, the heart’s weakened state struggles to maintain adequate pressure.
• Endocrine Disorders: Hormones play a big role in blood pressure regulation. Disorders like adrenal insufficiency (where the adrenal glands don’t produce enough hormones) or hypothyroidism (an underactive thyroid) can cause hypotension. In adrenal insufficiency, the lack of cortisol disrupts blood pressure stability.
• Severe Infections (Sepsis): When an infection spreads through the body, it can trigger sepsis, leading to widespread inflammation and a dangerous drop in blood pressure. This can escalate to septic shock, a medical emergency.
• Blood Loss: Losing a significant amount of blood—from an injury, surgery, or internal bleeding—reduces blood volume, causing hypotension. A car accident victim with internal injuries might experience this rapid decline.
• Medications: Some drugs, like diuretics (which remove excess water), beta-blockers (used for heart conditions), or even antidepressants, can lower blood pressure as a side effect. Always consult a doctor before adjusting medications.
• Pregnancy: During the first and second trimesters, blood pressure often drops due to hormonal changes and an expanding circulatory system. While usually harmless, severe drops might signal complications like an ectopic pregnancy.
• Neurological Disorders: Conditions affecting the autonomic nervous system, which regulates involuntary functions like blood pressure, can lead to hypotension. Examples include Parkinson’s disease or autonomic neuropathy (common in diabetes).
• Anaphylaxis: A severe allergic reaction—like to peanuts or bee stings—can cause a sudden, dramatic drop in blood pressure, potentially leading to anaphylactic shock.

Each cause requires a tailored approach, making it essential to pinpoint the root of the problem.

Symptoms of Hypotension

The symptoms of hypotension depend on how low the blood pressure drops and what’s causing it. Some people with readings below 90/60 mmHg feel fine, while others experience:

• Dizziness or lightheadedness (especially when standing up)
• Fainting (also called syncope)
• Blurred or tunnel vision
• Nausea
• Fatigue or weakness
• Confusion or trouble focusing
• Cold, clammy, or pale skin
• Rapid, shallow breathing

In severe cases, like shock, symptoms escalate to chest pain, shortness of breath, or unconsciousness. Picture an elderly person standing up from their chair and suddenly feeling dizzy—that’s a classic sign of orthostatic hypotension, which could lead to a fall if unchecked.

Symptoms can disrupt daily life, so recognizing them early is vital for seeking help.

Diagnosis of Hypotension

Diagnosing hypotension starts with confirming low blood pressure and then identifying why it’s happening. Here’s how it’s typically done:

• Blood Pressure Measurement: A device called a sphygmomanometer (the familiar cuff and gauge) measures blood pressure. Readings are often taken sitting and standing to catch drops like those in orthostatic hypotension.
• Medical History: Doctors ask about symptoms, recent illnesses, medications, and family history to uncover potential causes.
• Physical Exam: This checks for signs like dehydration (dry skin, rapid pulse) or heart issues (irregular heartbeat).
• Blood Tests: These can reveal anemia, infections, or electrolyte imbalances that might be contributing.
• Electrocardiogram (ECG): An ECG tracks the heart’s electrical activity, spotting irregularities that could lower blood pressure.
• Echocardiogram: This ultrasound shows the heart’s structure and function, helping diagnose valve problems or heart failure.
• Tilt Table Test: Used for orthostatic or neurally mediated hypotension, this test tilts a patient on a table while monitoring blood pressure and heart rate to see how the body reacts to position changes.

Diagnosis is a detective game—piecing together clues to find the culprit behind the low readings.

Treatment of Hypotension

Treatment varies based on the cause and severity. Here are the main approaches:

• Dehydration: Drinking more water or, in severe cases, receiving IV fluids can restore blood pressure. A patient dehydrated from the flu might need fluids in a hospital.
• Heart Problems: Medications to regulate heart rate or surgery for valve issues might be needed. A pacemaker could help someone with bradycardia.
• Endocrine Disorders: Hormone replacement, like corticosteroids for adrenal insufficiency, can stabilize pressure.
• Severe Infections: Sepsis requires antibiotics and IV fluids, sometimes with vasopressors (drugs that tighten blood vessels) in emergencies.
• Blood Loss: Transfusions or surgery to stop bleeding address this cause directly.
• Medications: If a drug is to blame, a doctor might adjust the dose or switch it. For hypotension itself, drugs like fludrocortisone (to retain sodium) or midodrine (to constrict vessels) can help.
• Lifestyle Changes:
• Increase Fluid and Salt Intake: Under a doctor’s guidance, more salt can boost blood volume (not for everyone, though).
• Compression Stockings: These keep blood from pooling in the legs.
• Stand Slowly: This prevents sudden drops.
• Small, Frequent Meals: Helps with postprandial hypotension.

Case Study: A 65-year-old woman with dizziness from orthostatic hypotension started wearing compression stockings and drinking more water. Her symptoms improved, reducing her fall risk.

Treatment is personalized—what works for one person might not for another.

Prevention of Hypotension

While not all cases are preventable, these steps can help:

• Stay Hydrated: Drink water regularly, especially in heat or during exercise.
• Balanced Diet: Include electrolytes like potassium (bananas, spinach) to support blood pressure.
• Exercise: Regular activity boosts circulation.
• Avoid Alcohol/Caffeine: Both can disrupt pressure regulation.
• Stand Slowly: Reduces the risk of orthostatic drops.
• Monitor Blood Pressure: Home checks help catch issues early, especially if you’re at risk.

Prevention is about small, consistent habits that keep your blood pressure steady.

Conclusion

Hypotension spans a spectrum—from a benign trait to a medical emergency. Knowing its causes, spotting its signs, and understanding how to manage it can make all the difference. Whether it’s drinking more water, adjusting medications, or seeking urgent care for severe symptoms, taking action is key. With the right knowledge and care, hypotension doesn’t have to hold you back.

 

Blood Clots and Thrombosis: The Silent Threat You Shouldn’t Ignore

Thrombosis is a serious medical condition characterized by the formation of blood clots within blood vessels, which can obstruct blood flow and lead to life-threatening complications. This in-depth article explores every facet of thrombosis, including its definition, types, causes, symptoms, diagnosis, treatment options, prevention strategies, statistical impact, and recent research developments. Written for a general audience, this article aims to provide a thorough yet accessible understanding of thrombosis, empowering readers with knowledge about this critical health issue.

---

## What is Thrombosis?

Thrombosis occurs when a blood clot, known as a thrombus, forms inside a blood vessel—either a vein or an artery—and disrupts the normal flow of blood. Under normal circumstances, blood clotting is a vital process that prevents excessive bleeding after an injury. However, when clots form inappropriately or fail to dissolve naturally, they can block blood vessels, leading to serious health consequences.

The severity of thrombosis depends on the location and size of the clot. A clot in a vein can impede blood returning to the heart, while a clot in an artery can prevent oxygen-rich blood from reaching vital organs. If a clot dislodges and travels through the bloodstream (becoming an embolus), it can cause emergencies like a pulmonary embolism or stroke. Understanding thrombosis is key to recognizing its risks and seeking timely medical intervention.

---

## Types of Thrombosis

Thrombosis is broadly classified into two categories based on where the clot forms: venous thrombosis (in the veins) and arterial thrombosis (in the arteries). Each type has distinct subtypes and implications.

### Venous Thrombosis

Venous thrombosis occurs in the veins, which return deoxygenated blood to the heart. The most common forms include:

- **Deep Vein Thrombosis (DVT):** This occurs when a clot forms in a deep vein, typically in the legs or pelvis. DVT can cause swelling and pain, but its greatest danger lies in its potential to break loose and travel to the lungs.

- **Pulmonary Embolism (PE):** A life-threatening condition where a clot (often from DVT) lodges in the pulmonary arteries of the lungs, blocking blood flow. PE requires immediate medical attention.

- **Superficial Thrombophlebitis:** A clot forms in a superficial vein near the skin’s surface, causing redness, tenderness, and inflammation. Though less severe than DVT, it still warrants treatment.

### Arterial Thrombosis

Arterial thrombosis occurs in the arteries, which carry oxygen-rich blood from the heart to the rest of the body. This type can lead to:

- **Heart Attack (Myocardial Infarction):** A clot blocks a coronary artery, cutting off blood supply to the heart muscle and causing tissue damage or death.

- **Stroke:** A clot obstructs an artery supplying the brain, leading to brain cell damage or death. Strokes can also result from emboli traveling to the brain.

- **Peripheral Arterial Disease (PAD):** Clots in the arteries of the limbs (usually the legs) restrict blood flow, causing pain, numbness, or tissue damage.

Each type of thrombosis presents unique challenges, making it essential to identify the specific condition for effective management.

---

## Causes and Risk Factors

Thrombosis results from a combination of factors that disrupt normal blood flow, damage blood vessel walls, or increase the blood’s tendency to clot. These factors are often explained by **Virchow’s triad**, a framework that highlights three key contributors:

1. **Stasis:** Slow or stagnant blood flow.

2. **Hypercoagulability:** An increased tendency for blood to clot.

3. **Endothelial Injury:** Damage to the inner lining of blood vessels.

### Common Risk Factors

Several conditions and lifestyle factors can increase the likelihood of thrombosis:

- **Immobility:** Prolonged periods of inactivity—such as bed rest after surgery, long flights, or extended sitting—slow blood flow, raising clot risk.

- **Surgery or Trauma:** Major surgeries (especially orthopedic ones like hip or knee replacements) or physical injuries can damage blood vessels and trigger clotting.

- **Cancer:** Certain cancers release substances that promote clotting, and chemotherapy can further elevate the risk.

- **Pregnancy and Hormonal Changes:** Pregnancy increases blood clotting factors to prevent excessive bleeding during childbirth, but this also raises thrombosis risk. Hormonal contraceptives and hormone replacement therapy have similar effects due to estrogen.

- **Genetic Conditions:** Inherited disorders like **Factor V Leiden mutation**, **prothrombin gene mutation**, or **antiphospholipid syndrome** make blood more prone to clotting.

- **Age:** The risk of thrombosis increases with age, particularly after 60, due to changes in blood vessels and circulation.

- **Obesity:** Excess weight puts pressure on veins and impairs circulation, heightening clot risk.

- **Smoking:** Tobacco use damages blood vessel linings and promotes clot formation.

- **Chronic Diseases:** Conditions like diabetes, high cholesterol, and hypertension can damage blood vessels over time, increasing susceptibility.

Understanding these risk factors can help individuals and healthcare providers take proactive steps to mitigate the chances of thrombosis.

---

## Symptoms of Thrombosis

The symptoms of thrombosis vary depending on the type, location, and severity of the clot. Some cases may even be asymptomatic, making awareness of potential signs critical.

### Symptoms of Venous Thrombosis

- **Deep Vein Thrombosis (DVT):**

  - Pain or tenderness, often in one leg, that may worsen when standing or walking.

  - Swelling in the affected leg or ankle.

  - Warmth and redness over the area of the clot.

  - Note: Up to 50% of DVT cases may show no symptoms until complications like PE arise.

- **Pulmonary Embolism (PE):**

  - Sudden shortness of breath that worsens with activity or deep breathing.

  - Sharp chest pain, especially when inhaling.

  - Rapid heart rate or palpitations.

  - Coughing, sometimes with blood.

  - Fainting or lightheadedness due to reduced oxygen levels.

- **Superficial Thrombophlebitis:**

  - Redness and inflammation along the affected vein.

  - Tenderness or a hard, cord-like feeling under the skin.

  - Mild swelling in the area.

### Symptoms of Arterial Thrombosis

- **Heart Attack:**

  - Intense chest pain or pressure, often described as a squeezing or heavy sensation.

  - Pain radiating to the arm, jaw, neck, or back.

  - Shortness of breath, sweating, nausea, or dizziness.

- **Stroke:**

  - Sudden numbness or weakness, especially on one side of the body (face, arm, or leg).

  - Difficulty speaking or slurred speech.

  - Vision problems, such as double vision or loss of sight in one eye.

  - Sudden severe headache or loss of coordination.

- **Peripheral Arterial Disease (PAD):**

  - Cramping or pain in the legs during activity (intermittent claudication) that improves with rest.

  - Numbness, coldness, or discoloration in the affected limb.

  - Slow-healing sores or infections due to poor blood flow.

Recognizing these symptoms early can be life-saving, as prompt treatment significantly improves outcomes.

---

## Diagnosis of Thrombosis

Diagnosing thrombosis involves a combination of clinical evaluation and specialized tests to confirm the presence, location, and extent of a clot. Doctors begin with a physical exam and a review of the patient’s medical history and risk factors.

### Common Diagnostic Tests

- **Ultrasound (Duplex Ultrasonography):**

  - A non-invasive test that uses sound waves to visualize blood flow in the veins or arteries. It’s the primary tool for diagnosing DVT, showing blockages or slowed circulation.

- **D-Dimer Test:**

  - A blood test that measures levels of D-dimer, a protein fragment released when a clot dissolves. Elevated levels suggest a clot may be present, though further imaging is needed for confirmation.

- **Computed Tomography (CT) Scan:**

  - Provides detailed images of blood vessels and organs. A CT pulmonary angiogram is commonly used to diagnose PE by highlighting blockages in the lung arteries.

- **Magnetic Resonance Imaging (MRI):**

  - Offers high-resolution images of blood vessels and tissues, useful for detecting clots in complex cases or when radiation (from CT) must be avoided.

- **Venography or Arteriography:**

  - Involves injecting a contrast dye into the blood vessels, followed by X-rays to visualize clots. These invasive tests are less common but highly accurate.

- **Echocardiogram:**

  - An ultrasound of the heart that can detect clots or assess damage from a heart attack or PE-related strain.

Accurate diagnosis ensures that treatment is tailored to the specific type and severity of thrombosis, minimizing complications.

## Treatment of Thrombosis

The goals of thrombosis treatment are to prevent the clot from growing, reduce the risk of complications (like embolization), and prevent new clots from forming. Treatment varies based on the clot’s location, size, and the patient’s overall health.

### 1. Anticoagulant Medications

- **How They Work:** Often called "blood thinners," anticoagulants (e.g., heparin, warfarin, rivaroxaban, apixaban) don’t dissolve existing clots but prevent them from enlarging and reduce the risk of new clots.

- **Use Cases:** The first-line treatment for DVT and PE, typically administered for 3-6 months or longer in recurrent cases.

- **Pros and Cons:** Effective and widely used, but require monitoring (especially warfarin) due to bleeding risks.

### 2. Thrombolytic Therapy

- **How It Works:** Known as "clot busters" (e.g., alteplase, streptokinase), these drugs actively dissolve clots by breaking down fibrin, the protein that holds clots together.

- **Use Cases:** Reserved for severe cases like massive PE, large DVT, or acute heart attack/stroke where rapid clot removal is critical.

- **Pros and Cons:** Fast-acting but carries a significant risk of bleeding, limiting its use to emergencies.

### 3. Surgical Interventions

- **Thrombectomy:** Surgical removal of a clot, performed when medications fail or are contraindicated (e.g., in patients with bleeding disorders).

- **Inferior Vena Cava (IVC) Filter:** A small device implanted in the vena cava (a major vein) to trap clots before they reach the lungs. Used in patients unable to take anticoagulants.

- **Pros and Cons:** Effective in specific scenarios but invasive and reserved for high-risk cases.

### 4. Supportive Measures

- **Compression Stockings:** Worn on the legs to reduce swelling and prevent blood pooling in DVT patients.

- **Pain Management:** Medications to relieve discomfort, especially in superficial thrombophlebitis or DVT.

Treatment plans are individualized, often combining medications with lifestyle adjustments for optimal recovery.

---

## Prevention of Thrombosis

Preventing thrombosis is especially important for those at high risk, such as individuals with a history of clots, recent surgery, or chronic conditions. Prevention strategies fall into two categories: lifestyle changes and medical interventions.

### Lifestyle Changes

- **Stay Active:** Regular physical activity, such as walking or stretching, improves circulation and reduces stasis.

- **Avoid Prolonged Immobility:** During long flights, car trips, or hospital stays, take breaks to stand, stretch, or walk every 1-2 hours.

- **Quit Smoking:** Eliminating tobacco use repairs blood vessel damage and lowers clotting risk.

- **Maintain a Healthy Weight:** Weight loss reduces pressure on veins and enhances blood flow.

- **Stay Hydrated:** Adequate fluid intake prevents blood from thickening, supporting healthy circulation.

### Medical Preventive Measures

- **Anticoagulants:** Prescribed prophylactically for high-risk individuals, such as post-surgical patients or those with genetic clotting disorders.

- **Compression Stockings:** Recommended for hospitalized patients, pregnant women, or those with varicose veins to prevent DVT.

- **Regular Checkups:** Monitoring chronic conditions (e.g., cancer, diabetes) and managing risk factors with a healthcare provider.

Prevention is a proactive process, blending personal habits with medical guidance to minimize thrombosis risk.

## Statistics and Public Health Impact

Thrombosis is a major global health concern with significant morbidity, mortality, and economic consequences. Key statistics highlight its scope:

- **Prevalence:** In the United States, venous thromboembolism (VTE), which includes DVT and PE, affects approximately 300,000 to 600,000 people annually (1-2 per 1,000).

- **Mortality:** PE contributes to about 100,000 deaths per year in the U.S., making it one of the leading preventable causes of hospital-related death.

- **Economic Costs:** The annual cost of managing VTE in the U.S. exceeds $10 billion, factoring in hospitalizations, medications, and lost productivity.

- **Underdiagnosis:** Many cases remain undetected, especially in asymptomatic individuals or those with atypical symptoms, complicating prevention efforts.

These figures underscore the need for greater awareness, early detection, and effective prevention strategies.

## Summary and Key Points

Thrombosis is a complex and potentially deadly condition caused by blood clots forming in veins or arteries. Its types—venous (e.g., DVT, PE) and arterial (e.g., heart attack, stroke)—carry distinct risks and symptoms, driven by factors like immobility, genetics, and chronic diseases. Early recognition of symptoms, such as leg swelling or chest pain, can prompt timely diagnosis through tests like ultrasound or CT scans. Treatment ranges from anticoagulants to surgery, while prevention hinges on lifestyle changes and medical interventions. With millions affected worldwide and ongoing research driving progress, understanding thrombosis is more critical than ever.

### Key Takeaways

- Thrombosis involves blood clots obstructing vessels, with venous and arterial forms.

- Risk factors include immobility, surgery, cancer, and genetics.

- Symptoms vary by type but can escalate quickly, requiring urgent care.

- Diagnosis relies on imaging and blood tests; treatment includes "blood thinners" and clot removal.

- Prevention combines activity, healthy habits, and medical support.

- Research continues to refine tools and therapies for this widespread condition.

"Heart Matters: Tackling Cardiovascular Diseases Globally with Advances & Solutions"

 

Cardiovascular Diseases -

*Introduction -

Cardiovascular diseases (CVDs) encompass a group of disorders of the heart and blood vessels that are leading causes of morbidity and mortality worldwide. This comprehensive document explores the epidemiology, anatomy and physiology, risk factors, pathophysiology, clinical presentations, diagnostic methods, management strategies, preventive measures, and future directions in the field of cardiovascular health. The content aims to provide an in-depth understanding, at a level suitable for medical professionals and health science students.

Epidemiology

• Global Burden: According to the World Health Organization (WHO), CVDs account for an estimated 17.9 million deaths annually, representing 32% of all global deaths. Of these, 85% are due to heart attack and stroke. Low- and middle-income countries bear over three quarters of these deaths.
• Regional Variation: Incidence and prevalence vary by region, influenced by socioeconomic factors, healthcare access, and population aging. High-income nations have seen declines in CVD mortality due to preventive strategies and advanced treatments, whereas developing regions experience rising rates.
• Trends Over Time: The last four decades have witnessed an epidemiological transition: decreased communicable disease mortality but increasing chronic diseases such as CVD, especially in urbanizing societies.

Anatomy and Physiology of the Cardiovascular System

• Heart Structure: The heart comprises four chambers (two atria, two ventricles), valves (mitral, tricuspid, aortic, pulmonary), and the conduction system (SA node, AV node, bundle branches, Purkinje fibers).
• Blood Vessels: Arteries, arterioles, capillaries, venules, and veins constitute the vascular network, facilitating oxygen and nutrient delivery, and waste removal.
• Cardiac Cycle: Systole (ventricular contraction) and diastole (ventricular relaxation) phases, regulated by electrical impulses and biomechanical feedback.
• Hemodynamics: Principles of pressure, flow (cardiac output), resistance (vascular tone), and compliance underpin normal cardiovascular function.

Risk Factors

Modifiable Risk Factors

1. Hypertension: Chronic elevation of arterial blood pressure is a major driver of endothelial damage and left ventricular hypertrophy.
2. Dyslipidemia: Elevated LDL cholesterol, low HDL cholesterol, and hypertriglyceridemia contribute to atherogenesis.
3. Diabetes Mellitus: Both type 1 and type 2 diabetes accelerate atherosclerotic processes and microvascular complications.
4. Tobacco Use: Smoking induces oxidative stress, thrombogenic changes, and vascular inflammation.
5. Unhealthy Diet: Diets high in saturated fats, trans fats, and sodium increase CVD risk; insufficient fruits and vegetables intake deprives protective micronutrients.
6. Physical Inactivity: Sedentary lifestyle contributes to obesity, insulin resistance, and adverse lipid profiles.
7. Obesity: Central adiposity correlates with metabolic syndrome and pro-inflammatory states.
8. Alcohol Consumption: Excessive intake raises blood pressure and triglycerides; moderate consumption shows a complex J-shaped relationship.

Non-Modifiable Risk Factors

1. Age: Risk increases with advancing age due to cumulative vascular damage.
2. Sex: Men are at higher risk at younger ages; women’s risk rises post-menopause.
3. Family History and Genetics: Genetic predispositions such as familial hypercholesterolemia significantly elevate lifetime risk.
4. Ethnicity: Certain ethnicities, such as South Asians, have higher susceptibility to CVD due to genetic and cultural factors.

Pathophysiology

• Atherosclerosis: Initiation by endothelial injury, followed by fatty streak formation, inflammation, smooth muscle proliferation, and fibrous plaque development.
• Thrombosis: Plaque rupture triggers platelet aggregation and coagulation cascade, leading to vessel occlusion.
• Myocardial Ischemia and Infarction: Imbalance between oxygen supply and demand causes angina; sustained ischemia leads to myocardial necrosis.
• Heart Failure: Resultant of systolic dysfunction (reduced ejection fraction) or diastolic dysfunction (preserved ejection fraction) from chronic pressure or volume overload.
• Arrhythmogenesis: Structural remodeling and ischemia disrupt electrical conduction, causing atrial fibrillation, ventricular tachycardia, or fibrillation.
• Hypertensive and Valvular Changes: Chronic pressure overload induces left ventricular hypertrophy; valvular pathologies (stenosis or regurgitation) provoke chamber dilation and failure.
• Stroke and Peripheral Vascular Disease: Cerebral or limb ischemia from atherothrombosis or embolism shares similar mechanisms.
