What causes heart disease? The answer to this question varies from person to person. In general though, people who are over forty, women, African Americans, and those who have diabetes, kidney disease, or high cholesterol are at greater risk. However, these are only risk factors for the disease itself; what causes heart disease in one person may not affect someone else who are the same age, weight, and cholesterol level. Can you prevent a heart attack? Yes, and no. High blood pressure (hypertension) is one of the main risk factors for cardiovascular disease. Some other risks for cardiovascular disease, such as high blood cholesterol (HDL), can also be influenced by family medical history. But there's plenty that you can do, such as eating right, getting regular exercise, reducing your stress levels, taking your prescription medications as directed and minimizing your tobacco use, to reduce your chances for developing coronary artery disease. There are many different types of cancer leading cause death around the world. One of the most common types of cancer leading cause death is lung cancer. Lung cancer has many different types, such as adenocarcinoma, mesothelioma, pleural mesothelioma, lung carcinoma, and non-Hodgkins lymphoma. Other types of cancer leading cause death include cervical cancer, liver cancer, pancreatic cancer, leukemia, ovarian cancer, colon cancer, and stomach cancer. What causes coronary artery disease? Coronary artery disease or coronary artery blockage is the most common type of heart disease. The arteries that supply blood to the heart become narrowed or blocked, sometimes due to plaque buildup. This plaque buildup narrows the arteries and is one of the primary causes of heart attack. Other causes of this type of heart attack are sudden cardiac arrest, rheumatic fever, atherosclerosis, congenital heart defects, or high cholesterol levels in the blood stream. Plaque build-up is usually more common in women than men. How is heart disease diagnosed? Heart disease can have many different manifestations. Symptoms of heart failure may include a feeling of shortness of breath, palpitations, fatigue, dizziness, nausea, sweating, nausea, diarrhea, and vomiting. These symptoms are commonly mistaken for other illnesses, so if you experience any of them, it is important to see a doctor immediately. Chest x-rays and echocardiograms may also be conducted in order to identify any problem areas. Chest x-rays will help determine whether there are any abnormalities in the heart's dimensions. What causes diabetes? Diabetes is a condition in which the body cannot produce or use insulin properly. This condition is associated with many risk factors for heart disease. Those who have family histories of diabetes are at higher risk than others, but even healthy individuals can develop the condition if they do not control their diabetes properly.
