What is Myocardial Infarction?

A myocardial infarction happens when one or more coronary arteries become blocked, often by a blood clot or a buildup of plaque. The lack of oxygenated blood to the heart can lead to permanent tissue damage if not treated quickly.

Signs and Symptoms

• Chest pain or discomfort
• Shortness of breath
• Nausea or vomiting
• Cold sweat
• Fatigue
• Pain in arms, neck, jaw, or back

Causes and Risk Factors

Common causes include atherosclerosis (plaque buildup), high blood pressure, smoking, diabetes, obesity, and a sedentary lifestyle. Family history and age (men over 45 and women over 55) also increase risk.

Diagnosis

Doctors use ECGs (electrocardiograms), blood tests (troponin levels), echocardiograms, and coronary angiography to diagnose heart attacks. Early detection is crucial for minimizing damage.

Treatment Options

Immediate treatments include:

• Aspirin to thin blood
• Thrombolytic therapy
• Angioplasty and stenting
• Coronary artery bypass grafting (CABG)

Medications such as beta-blockers, ACE inhibitors, statins, and antiplatelet drugs are used for long-term management.

Recovery and Rehabilitation

Cardiac rehabilitation programs offer supervised exercise, lifestyle education, and counseling. Most patients recover within 6–12 weeks with proper support and medical care.

Prevention Tips

• Eat a heart-healthy diet rich in fruits, vegetables, and whole grains
• Exercise at least 30 minutes a day
• Quit smoking
• Maintain a healthy weight
• Control blood pressure, cholesterol, and diabetes

Lifestyle and Diet

Follow the Mediterranean or DASH diet. Include foods like salmon, oats, berries, olive oil, nuts, and leafy greens. Limit red meat, sugar, and processed foods.
