How to Prevent and Recognize a Heart Attack: Evidence-Based Guidance

Research from the American Heart Association and Johns Hopkins Medicine highlights that 99% of heart attacks are linked to preventable risk factors. The key modifiable risks include:

Early Signs of Heart Attack: What Science Says About Saving Lives

• High blood pressure: The most common contributor to heart attacks. Regular monitoring and treatment are essential.

• High cholesterol: Elevated LDL cholesterol leads to plaque buildup in arteries.

• Smoking: Strongly linked to coronary artery disease. Quitting reduces risk significantly.

• Diabetes and obesity: Both increase cardiovascular strain and risk.

• Poor diet and inactivity: A balanced diet rich in fruits, vegetables, whole grains, and regular exercise lowers risk.

• Stress and excessive alcohol: Both can elevate blood pressure and weaken heart health.

Non-modifiable risks include age, family history, gender, and ethnicity, but managing lifestyle factors can dramatically reduce overall risk.

Recognition: Early Warning Signs

According to the American Heart Association’s 2025 guidelines, heart attacks often begin with subtle symptoms before escalating. Common signs include:

• Chest pain or pressure: Tightness, squeezing, or heaviness.

• Pain in arms, back, neck, jaw, or stomach.

• Shortness of breath: Even without chest pain.

• Cold sweats.

• Nausea, dizziness, or extreme fatigue: Especially common in women.

The American College of Cardiology’s Early Heart Attack Care (EHAC) program stresses that heart attacks have beginnings—recognizing these early signs can prevent severe damage.

Immediate Action

If you suspect a heart attack:

• Call emergency services immediately (911 in the U.S.). Do not drive yourself.

• Stay calm and follow dispatcher instructions.

• Use CPR or an AED if someone collapses and is unresponsive.

Emergency responders can begin treatment en route, improving survival rates.

• The NIH’s National Heart, Lung, and Blood Institute (NHLBI) funds long-term studies showing that lifestyle interventions and medical management (like statins and antihypertensives) significantly reduce heart attack incidence.

• Johns Hopkins Medicine emphasizes that coronary artery disease is preventable and that early treatment of hypertension and cholesterol is critical.

• Medical News Today reports that tackling just four risk factors—blood pressure, cholesterol, smoking, and diabetes—could prevent nearly all heart attacks.

Heart attacks can often be prevented and, when they occur, recognized early. The combination of lifestyle management, awareness of warning signs, and immediate emergency response is the most effective strategy.
