A heart attack, also known as a myocardial infarction, occurs when blood flow to a part of the heart muscle is blocked, usually by a buildup of plaque in the coronary arteries. This blockage prevents oxygen-rich blood from reaching the heart tissue, leading to damage or death of the muscle cells.
Causes and Risk Factors:
The primary cause is coronary artery disease, where fatty deposits (plaque) narrow the arteries. Risk factors include high blood pressure, high cholesterol, smoking, diabetes, obesity, a sedentary lifestyle, family history of heart disease, and age (especially over 65). Stress and excessive alcohol consumption can also contribute.
Symptoms:
Common signs include chest pain or discomfort that may feel like pressure, squeezing, or fullness; pain radiating to the arms, neck, jaw, back, or stomach; shortness of breath; cold sweats; nausea; lightheadedness; and fatigue. Women may experience atypical symptoms like jaw pain or extreme fatigue without chest pain.
Diagnosis and Treatment:
Doctors use tests such as ECG, blood tests for enzymes, echocardiograms, or angiograms to diagnose a heart attack. Immediate treatment involves medications like aspirin, clot-busters, or beta-blockers, and procedures such as angioplasty or stent placement to restore blood flow. In severe cases, surgery like bypass grafting may be required.
Prevention:
Adopt a heart-healthy lifestyle by eating a balanced diet rich in fruits, vegetables, whole grains, and lean proteins; exercising regularly (at least 150 minutes of moderate activity per week); maintaining a healthy weight; quitting smoking; managing stress; controlling blood pressure and cholesterol through medication if needed; and getting regular medical check-ups.
Emergency Response:
If a heart attack is suspected, call emergency services immediately. Administer CPR if the person is unresponsive, and keep them calm and seated until help arrives. Early intervention can save lives and minimize heart damage.

Options:
A. Acid reflux
B. Migraine headache
C. Anxiety attack
D. All of the above
Answer: D
Explanation: Symptoms like chest pain can overlap with acid reflux, migraines, or anxiety, but a heart attack involves cardiac issues, requiring medical evaluation to differentiate.
6. Question: What role does cholesterol play in heart attacks?
Options:
A. It protects artery walls
B. High levels can lead to plaque formation in arteries
C. It prevents blood clotting
D. It increases heart rate beneficially
Answer: B
Explanation: Excess LDL cholesterol contributes to atherosclerosis, where plaque builds up in arteries, potentially blocking blood flow and triggering a heart attack.
7. Question: In women, what is a less common but possible symptom of a heart attack?
Options:
A. Jaw or back pain
B. Excessive sweating
C. Fatigue
D. All of the above
Answer: D
Explanation: Women may experience atypical symptoms like jaw pain, sweating, or fatigue due to differences in how heart attacks present, often related to hormonal or physiological factors.
8. Question: What is the primary cause of most heart attacks?
Options:
A. Viral infection
B. Coronary artery blockage
C. Overexertion during exercise
D. High body temperature
Answer: B
Explanation: A blockage in the coronary arteries, usually from a blood clot on a plaque, cuts off blood supply to the heart muscle, leading to tissue damage.
9. Question: How can diabetes increase the risk of a heart attack?
Options:
A. By improving insulin sensitivity
B. By damaging blood vessels and nerves
C. By reducing blood sugar levels
D. By enhancing heart muscle strength
