Causes of Heart Disease

Heart disease primarily stems from atherosclerosis—a buildup of fatty deposits (plaques) in the arteries, which narrows blood vessels and reduces oxygen supply to the heart. High blood pressure: Increases strain on arteries.

• High cholesterol: LDL ("bad" cholesterol) contributes to plaque formation.
• Smoking: Damages blood vessels and accelerates plaque buildup.
• Diabetes: Elevates blood sugar levels, damaging blood vessels.
• Obesity: Linked to metabolic disorders and inflammation.
• Genetics: Family history of heart disease increases susceptibility.

Symptoms of Heart Disease

Symptoms vary by condition but often include:

Heart Attack Symptoms

• Chest pain or discomfort (may feel like pressure or squeezing).
• Shortness of breath, nausea, cold sweat, lightheadedness.
• Pain radiating to the jaw, arm, or back.

Stroke Symptoms (FAST criteria)

• Face drooping, Arm weakness, Speech difficulty, Time to seek help.
• Sudden numbness, confusion, vision loss, or severe headache.

Other Symptoms

• Fatigue, swelling in legs, irregular heartbeat, or dizziness.

Treatment and Management

Medications

• Statins: Lower LDL cholesterol (e.g., atorvastatin).
• ACE Inhibitors: Relax blood vessels (e.g., lisinopril).
• Beta-Blockers: Reduce heart rate and blood pressure (e.g., metoprolol).
• Anticoagulants: Prevent blood clots (e.g., warfarin).

Procedures and Surgery

• Coronary Angioplasty/Stents: Open blocked arteries.
• Bypass Surgery: Diverts blood flow around blocked arteries.
• Valve Repair/Replacement: Fixes malfunctioning heart valves.

Lifestyle Interventions

• Diet: Low-sodium, high-fiber, and plant-based meals.
• Exercise: 150+ minutes of weekly moderate activity.
• Smoking Cessation: Reduces arterial damage.

Prevention Strategies

• Monitor Risk Factors: Regular checks for blood pressure, cholesterol, and glucose.
• Cardiac Rehabilitation: Supervised exercise and education post-heart events.
• Air Quality: Avoid pollution, which exacerbates cardiovascular risks.

Comparison of Heart Attack vs. Stroke Symptoms

Global Burden of Cardiovascular Disease

• 19.8 million deaths in 2022 (32% of global deaths), with 85% due to heart attacks or strokes 7.
• 38% of premature NCD deaths (under 70) are CVD-related.

By addressing modifiable risk factors and adopting early detection strategies, the impact of heart disease can be significantly reduced.

FAQs 

1. What are the earliest symptoms of cardiac disease?

Usually, chest pain, breathlessness, fatigue, or palpitations—see a doctor early.

2. Can women experience different heart attack symptoms?

Yes—women often have subtle symptoms such as nausea, jaw/back pain, and extreme tiredness.

3. How quickly should I act if I suspect a cardiac issue?

Seek emergency help immediately if chest pain, breathlessness, or collapse occurs.

4. Is all heart pain serious?

Not always, but persistent or severe pain should never be ignored; consult your doctor.

5. What simple steps lower my heart risk?

Eat heart-friendly foods, stay active, don’t smoke, check blood pressure/cholesterol regularly.
