If you are unsure about the relationship between coronary artery disease and hypertension, then here's some information for you. The European Heart Journal reports that hypertension or high blood pressure is a well-established risk factor for coronary heart disease. Coronary heart disease is the most common form of heart disease, and it can begin as early as childhood or as a teenager. This particular disease occurs when one or more coronary arteries, which transport oxygen rich blood to the heart, become clogged. This happens due to the deposits of cholesterol and plaque inside the arteries. The progressive accumulation of plaque on the coronary arteries is called atherosclerosis.
Relation Between Coronary Artery Disease and Hypertension
Hypertension is high blood pressure. Blood pressure can be defined as the force of the blood against the walls of the arteries. The force is generated with each heartbeat, when the blood is pumped from the heart into the blood vessels. Each time the heart contracts or relaxes, force is generated inside the arteries. As the artery hardens or becomes thick, it becomes difficult for blood to pass through it, and so the pressure may rise. This may result in hypertension. However, there are no clinical evidences that coronary artery disease causes hypertension. It is only a postulation because studies suggest that hypertension has no known specific causes.
On the contrary, studies report that hypertension or high blood pressure can considerably increase a person's risk of coronary heart disease. So we can say that coronary artery disease and hypertension are closely related to each other. Individuals with a history of coronary artery disease with a combination of moderate hypertension are at high risk.
According to a clinical study result on the relationship between coronary artery disease and hypertension, at the same blood pressure levels, the mortality rates from coronary heart disease varied significantly among the populations.
After deep numerical research of the systolic and diastolic blood pressure, a linear relationship between coronary artery disease and hypertension was established. The result outlined that lower the blood pressure, the lower is the risk of death from coronary heart disease and vice versa. So we can conclude that any increase in the blood pressure is associated with an increase in risk of coronary heart disease mortality.
Further, clinical reports say that this relationship is not dependent upon the blood pressure levels that the individuals have. You can consult a well experienced cardiologist to learn more about this issue.
