What Are The Causes Of Heart Attacks

Myocardial infarction or a heart attack is a life-threatening medical emergency. It occurs when your heart muscles begin to die due to a lack of blood flow. Your doctor must restore blood flow quickly. A heart attack can lead to permanent damage or even death. A certified cardiologist in Mumbai, Delhi or any city near you can help understand underlying factors that can cause a heart attack.

Causes Of Heart Attack 

Blockage 

Coronary arteries (arteries that supply blood to the heart muscle) blockages commonly cause a heart attack. Blockages usually occur due to plaque (cholesterol-containing deposits) lodging in the arteries, which narrows the arteries, hindering blood flow to the heart. These blockages might lead to coronary artery disease, i.e. when one or more coronary arteries get blocked. However, it only accounts for 5% of all heart attacks.  

Drug misuse 

Misuse of stimulating drugs such as amphetamines (speed), cocaine, and methamphetamines (crystal meth) can cause the narrowing of coronary arteries, limiting blood supply and resulting in a heart attack. Cocaine is the most common cause of sudden death by a heart attack in young people. 

Lack of oxygen in the blood (hypoxia) 

Loss of normal lung function or carbon monoxide poisoning might decrease the oxygen levels in the blood; thus, the heart will receive unoxygenated blood. Further, it might result in damaged heart muscles, initiating a heart attack.

Electrolyte imbalance 

Sometimes, mineral levels in your blood might fluctuate, causing an electrolyte imbalance. As a result, people might experience irregular heart rates, high blood pressure or even heart failure. 

Rare medical conditions and infections 

Certain rare conditions might cause an unusual narrowing of blood vessels. Viral infections like Covid-19 might also affect the functioning of the heart muscle, which in turn might trigger a heart attack. 

Embolism or Blood clots  

Embolism, formation of an air bubble and a blood clot in a coronary artery might cause a heart attack 

Lifestyle factors 

Consuming an unhealthy diet which has high salt content, sugar and fat. Additionally, smoking, drinking excess alcohol, and limited physical activity might be the underlying factors behind many conditions leading to a heart attack.  

Book Doctor's Appointment 

If you have high cholesterol or blood pressure levels you should visit a cardiologist in Mumbai to check your heart health regularly. You can also book a doctor's appointment for a quick consultation. 

Moreover, maintaining healthy body weight, making healthy lifestyle choices and getting regular check-ups can reduce your risk of a heart attack. Visit a cardiologist in Mumbai or book a doctor’s appointment near you for better advice.
