Heart Disease & Disorders

Heart disease covers a multitude of conditions and diseases affecting the heart. As it encompasses a wide range of disorders it is understandably the leading cause of death worldwide including the United States, England and Canada. Congenital defects are heart conditions that are genetic diagnosed at birth or possibly later in life. However, many types of cardiovascular and heart disease can be prevented by healthy lifestyle choices. For example, hardening of the arteries can be caused by being overweight, poor diet, high cholesterol, lack of exercise and smoking. Other conditions, such as arrhythmia’s can be caused or exacerbated by stress and too much caffeine.
Suspicious you might have a heart condition? Experiencing shortness of breath, chest pain, light-headedness or fainting could signal a problem and should be followed with a visit to your doctor. Risk factors include age, having a family history of heart disease, obesity, diabetes and other unhealthy lifestyle habits such as smoking, drinking or stress.
Learn more about the various heart diseases and conditions that could affect you or a loved one. You’ll find in-depth information on the causes, symptoms and treatment of coronary artery disease, congestive heart failure, heart palpitations and arrhythmia’s, murmurs, high blood pressure, heart attacks and the many other diseases that affect the heart and surrounding blood vessels.

Intermittent High Blood Pressure

Blood pressure can suddenly rise in a person who has not been diagnosed as hypertensive and in those who are receiving treatment for it. High blood pressure usually occurs without symptoms but complications may eventually set in. Learn more about intermittent high blood pressure and its treatment.

What Are Premature Atrial Complexes?

Premature atrial complexes are caused by abnormal electrical impulses transmitted by the atria (either of the upper chambers of the heart). The abnormal electrical impulses cause contractions of the upper chamber of the heart earlier than expected. Such premature beats are generally harmless.

Angina Pectoris and Pathophysiology

Although heart attack due to coronary disease is a common cause of death in adults, less than 20 percent of patients experience chest pains. How do chest pains related to heart disease evolve? Learn more about angina pectoris and pathophysiology of myocardial ischemia.
