Heart attack is the biggest killer in modern times. A heart attack causes when the flow of oxygen-rich blood to a particular section of the heart muscles suddenly become blocked, and the heart can not get sufficient oxygen.
Another name for a heart attack is cardiac infarction, myocardial infarction, and coronary thrombosis. Cardiovascular diseases killed 18.4 million men and women in 2012 that is 3 in every 10 deaths. Of these, 6.9 million people died of ischaemic heart disease and 7.1 million from stroke.
In congestive heart failure (CHF), the heart muscles become weaker. When the heart muscles are weakened, they are less forceful in pumping the blood throughout the body. Less blood moves out of the heart.
Causes Of Heart Attack
There are several reasons for heart attack. Here we have jotted down a few common reasons.
• In Most cases, the heart attacks occur as a result of coronary heart disease (CHD).
• CHD (coronary heart disease) is a serious condition in which a waxy substance called plaque builds up inside of the coronary arteries. The arteries supply oxygen-rich blood to your heart.
• Nicotine and Carbon Monoxide (from the smoke) both put a strain on our heart by making it act faster. They also enhance the risk of blood clots. Several Other chemicals in cigarette smoke severely damage the linings of the coronary arteries, leading to furring of the arteries. If you smoke, you enhance the risk of developing heart disease by 25%.
• If you have a diet rich in saturated fat, the blood cholesterol levels will rise. This leads to enhanced probability of heart failure.
• Having poorly controlled hypertension or high blood pressure can weaken the coronary arteries, making them vulnerable to CHD. The higher our blood pressure, the greater the risks of heart attacks and CHD.
• The older one gets; the more likely one is to develop some degree of CHD. Men are more likely to have a heart failure than women.
• If you have a first-degree relative with a history of heart disease – such as heart attack, angina, and stroke, you are thrice as likely to develop similar heart problems, compared to the general population.
• The enhanced levels of blood glucose associated with type 1 diabetes can damage the coronary arteries, making them more vulnerable to coronary artery disease (CHD). It is estimated that men and women with diabetes are more likely to develop CHD than the general population.
• Being overweight or obese directly increases the risks of heart attacks and CHD.
• Lack of exercise is linked to an increased risk of heart attacks and CHD.
• Excessive alcohol consumption can cause hypertension or high blood pressure and enhanced blood cholesterol levels, thereby enhancing the chance of developing CHD.
• Scientists have found that exposure to air pollution can cause a significant rise in the chance of developing coronary artery disease and, in turn, heart attacks.>>>>READ MORE
