Heart Attack
A heart attack, medically known as a myocardial infarction, occurs when blood flow to a part of the heart muscle is blocked, leading to tissue damage due to lack of oxygen. This blockage is most commonly caused by coronary artery disease (CAD), where plaque builds up in the arteries, narrowing them and restricting blood flow. Less frequently, heart attacks can result from severe spasms of the coronary arteries or other conditions that disrupt blood supply.
Heart Attacks in the U.S
Approximately 805,000 people in the U.S. experience a heart attack each year. Of these, about 605,000 are a first heart attack, and the remaining 200,000 are recurrent heart attacks.
Heart Disease and Death Rates
The every cause of death in the US is heart disease, including heart attacks For both men and women, heart disease is responsible for 1 in 4 deaths each year.

What are the risk factors of heart attack?
Risk Factor of heart disease
Several factors can increase the likelihood of experiencing a heart attack: Traditional Risk Factors: High blood pressure, high cholesterol levels, smoking, diabetes, and obesity are well-established contributors. Emerging Risk Factors: Conditions like metabolic syndrome and chronic kidney disease are increasingly recognized as significant risks25. Demographic Factors: Age and gender play roles; men generally face higher risks earlier in life, but women's risks increase significantly post-menopause. Racial disparities also exist, with Black Americans experiencing higher rates of heart disease.
Risk Factors
High blood pressure (hypertension)
High cholesterol
Smoking
Obesity and poor diet
Physical inactivity
Excessive alcohol consumption
Family history of heart disease
Diabetes
Stress and mental health issues (chronic stress, anxiety, etc.)
Immediate Response and Treatment
Medications such as blood thinners (antiplatelets), pain relievers, and clot-busting drugs Call Emergency Services: Dial 911 immediately. Stay Calm: Reassure the person experiencing symptoms until help arrives.
