What is Cardiac Disease and what causes it?
What Is Cardiac Disease?
Cardiac disease refers to a class of diseases that affect the heart and blood vessels. It encompasses the veins, capillaries, and arteries. Risk factors for cardiovascular disease may include age, gender, tobacco use, high blood pressure, diabetes, and family history. In addition, obesity, excess sugar consumption, sedentary lifestyle, and air pollution also count as risks.
What Causes Cardiac Disease?
Atherosclerosis causes all cardiovascular diseases. Atherosclerosis occurs when arteries narrow after a gradual buildup of fatty materials on arterial walls. As arteries narrow over time, blood that supplies oxygen can’t make it to the heart. This can result in angina, with symptoms of discomfort or pain in the chest.
If a piece of atheroma breaks away from the arteries, it can create a blood clot. Moreover, if a blood clot blocks a coronary artery, blood supply to the heart will be cut off. In addition, this can cause permanent damage to the heart muscle in what is known as a heart attack. Thus, if a blood clot blocking an artery travels to the brain, it can cut off blood supply to cause a stroke.
