A heart attack occurs when the blood supply to the heart muscle is interrupted. The heart needs a constant supply of oxygenated blood, as do other organs and tissues in the body.
If the heart does not get an adequate supply of blood, the heart muscles will be damaged and eventually the heart will not be able to circulate blood throughout the body.
Below are the causes of heart attacks:
Coronary heart disease
Coronary heart disease is the main cause of heart attacks. Coronary heart disease is a condition in which one or more of the blood vessels that supply blood to the heart (coronary arteries), are blocked by cholesterol plaque buildup (atherosclerosis) and blood clots.
Drug abuse
of addictivedrugs,such as cocaine, amphetamine,and methamphetamine,can cause constriction of the coronary arteries, triggering a heart attack.
Lack of oxygen in the blood (hypoxia)
Oxygen levels in the blood can decrease due to carbon monoxide poisoning or impaired lung function. As a result, the heart muscle will be deprived of oxygen and a heart attack occurs.
Risk Factors
Coronary heart disease is the main cause of heart attacks. There are several conditions that are at risk of causing fat accumulation and narrowing of blood vessels (atherosclerosis) in coronary heart disease, including: Old
- age (men aged 45 years and over or women aged 55 years and over)
- Rarely exercise
- Smoking
- Suffering from hypertension
- Suffering from high cholesterol or triglycerides high
- Having diabetes
- Being obese
- Being stressed
- Having a family member who has had a heart attack
In addition, the risk of a heart attack is also higher in people who suffer from autoimmune diseases, such as lupus and women who develop preeclampsia during pregnancy.
