Cardiovascular diseases are considered group of diseases in which it affects almost a higher proportion of the population. This is because of several interlinked factors which are contributory to the development of these cardiovascular diseases. One of which is unhealthy lifestyle which includes poor eating habits that can lead to consumption of high caloric food choices, and lack of physical and regular exercises which can build or initiate formation of cholesterol plaques in the vessels which supplies blood to the different parts of the human body.

Also, another factor can be due to stress which puts the person into great deal of discomfort causing many biological alterations which may include high blood pressure. Moreover, cardiovascular diseases can lead to the development of heart attack. New research says that the severity of heart attack that a person may experience can be affected by the time of the day it occurs.

According to statistics, heart attack or coronary heart disease is considered one of the leading causes of deaths for both men and women in the United States. Heart attack is the failure of the heart to pump blood to the different parts of the human body because of the damages in the muscle of the heart itself. This damage is caused by the narrowing of vessels especially the coronary arteries which are responsible for supplying the muscle cells of the heart with nourishment and oxygen. When narrowing occurs, this result to limitation of blood supply leading to decreased in oxygen supply which in turn damages the heart.

The National Heart Lung and Blood Institute says that “Each year, about 1.2 million people in the United States have heart attacks, and many of them die. CHD, which often results in heart attacks, is the leading killer of both men and women in the United States. Many more people could survive or recover better from heart attacks if they got help faster. Of the people who die from heart attacks, about half die within an hour of the first symptoms and before they reach the hospital.”

The new study which was published online in the journal Circulation Research involve the analysis and examination of data gathered from about 1,000 patients who had heart attack. Researchers found out by observing the data that the greatest amount of injuries of heart attack acquired by the study subject occurred in between 1 a.m. to 5 a.m. time of the day. In addition, researchers discovered that the peak of the quantity of the heart injury which occurs during the said time period was about 82 per cent higher compared to the heart damage acquired bny other patients during different time of the day.

Moreover, according to study senior author Dr. Jay Traverse, a cardiologist at the Minneapolis Heart Institute, he said: “It is important to understand that the heart’s ability to protect itself against more severe damage varies over a 24-hour cycle. Identifying those protective changes may be particularly relevant for pharmaceutical manufacturers that are seeking to develop cardioprotective drugs.”
