Causes and Effects of Heart Attack

A heart attack is a global problem and occurs when the heart stops pumping blood due to blockage of blood flow. According to a report by American health experts, about 1 million people in America have heart attacks each year. Although the death ratio of heart attack has been reduced due to the latest treatments but still, it is a threat.

Causes of Heart Attack

1. Coronary Heart Disease

Majority of the heart attacks are due to coronary heart disease. It is a condition in which deposits of cholesterol blocks the arteries carrying blood to the heart, called coronary arteries. These cholesterol deposits are called plaques.

2. Drug Misuse

Many people around the world are drug addicts, but they are unaware of its consequences. . Various excitants like amphetamines and cocaine cause blockage in coronary arteries, leading to a heart attack.

3. Reduced Amount of Oxygen in Blood

The function of the heart is to pump blood to the whole body and for this, it needs an ample amount of oxygen. When the oxygen level in the blood reduces, myocardial infarction is the outcome. Blood oxygen level decreases due to carbon dioxide poisoning or dysfunction of lungs.

Effects of Heart Attack

Myocardial infarction is a fatal disease and has got various long-term and short-term effects. Here, we will discuss the most severe consequences of a heart attack.

1. Arrhythmia

Arrhythmia is a condition in which your heart beats abnormally. Symptoms of arrhythmia include palpitations, dizziness, and severe chest pain.

2. Rupturing of Heart

It causes the heart muscles and walls to rupture. The heart is damaged significantly and open-heart surgery is performed to treat the condition. Most of the victims of heart rupture die within 5 days of the rupturing.

3. Cardiogenic Shock

Cardiogenic shock is the more severe form of heart failure and occurs when the heart tissues are extensively damaged. As a result, the heart doesn’t pump enough blood to the body.

What do you need to do after a Heart Attack?

Effective treatment is required after a heart attack to open the blocked coronary arteries. Different blood tests are performed to measure the severity of the heart attack. Electrocardiogram (ECG) may also be performed after consultation with the doctor. If the heart attack has caused severe damage to the heart muscles, open-heart surgery is performed.
