What Factors Contribute to Cardiac Ischemia?

Cardiac ischemia, also known as myocardial ischemia, is a condition where blood flow is obstructed to the heart, leading to lack of oxygen into the heart. Cardiac ischemia is indicative of a partial or complete arterial blockage in the heart. Over time, the condition can reduce the ability of the cardiac muscles to pump blood, leading to several disorders.

Here is a look at some of the common reasons for cardiac ischemia-

• Atherosclerosis- This is a condition where excess cholesterol in the blood creates blockages in arterial walls. Under such a condition, the blood flow is restricted, which is why atherosclerosis is the most common cause of cardiac ischemia.

• Blood clot- The cholesterol plaques formed in atherosclerosis may rupture and lead to clot formation. The clot can suddenly lead to severe cardiac ischemia, causing a heart attack. In rare instances, a clot formed in other parts of the body may travel to the cardiac arteries.

• Spasms in coronary artery- A spasm can lead to tightening of the muscles in the chest causing restricted blood flow. However, such spasms are the least common cause for cardiac ischemia.

Risk factors for cardiac ischemia-

Here is a look at some factors that contribute to your likelihood of suffering from myocardial ischemia.

• Tobacco

• Diabetes

• High blood cholesterol levels

• High blood pressure

• Obesity

• High blood triglyceride

• Lack of exercise

• Large waist circumference

How can you prevent cardiac ischemia?

Lifestyle changes are the easiest way to avoid myocardial ischemia. Following a healthy diet with limited amount of cholesterol prevents clogging of arteries, allowing blood to pass to the heart.

Another important step in keeping cardiac ischemia at bay is to exercise regularly. This helps strengthen the heart muscles and ensure that it is able to pump blood without any problems. Furthermore, regular workout aids in shedding excess fats and cholesterol from the body.
