Often, experiencing one disease or condition can cause an increased risk for developing another condition. This is the case with heart disease. There are several diseases related to heart disease. These diseases can either lead to heart disease or commonly occur together.
People who have diabetes are at a greater risk for heart disease and stroke. This is because high blood glucose levels can increase the rate at which fatty deposits form along the walls of blood vessels, leading to atherosclerosis. Those with Type 2 diabetes especially may have increased risk factors, such as obesity, high cholesterol, and high blood pressure; all of which add to the risk of developing heart disease.
The same conditions that may lead to heart disease are the same conditions that may lead to stroke. Thus, if someone has already suffered a stroke, they are at a greater risk for developing heart disease. These risk factors include high blood pressure, high cholesterol, diabetes, smoking cigarettes, eating an unhealthy diet, being obese or overweight, and leading a sedentary lifestyle.
Irregular heartbeats are symptoms of cardiac dysrhythmia. These may occur as a result of heart disease, though they may also exist on their own. Irregular heartbeats can be a cause of heart failure and death, especially when they occur as a result of heart disease.
Hypertension and high cholesterol can also lead to heart disease. High blood pressure can cause the heart to become enlarged, cause the heart to beat irregularly, or cause the lungs to collect fluid. High cholesterol can lead to atherosclerosis. All of these can lead to diseases of the heart.
Cerebrovascular disease is caused by the hardening and narrowing of the blood vessels in the brain. It can become worse due to certain heart diseases. Those with cerebrovascular disease are also at an increased risk for heart disease as well.
Peripheral vascular disease is also related to heart disease, as they both share the same risk factors and causes. Peripheral vascular disease typically refers to a complete blockage in a large artery that occurs due to a narrowing and hardening of the arteries.
The bacteria that causes strep throat can ultimately lead to heart damage, specifically damage to the valves in the heart. In some cases, strep bacteria can release toxins that can result in scarlet fever. Scarlet fever can lead to rheumatic fever, which damages the heart.
