Cardiovascular disease is the most common cause of death in America. There are risk factors for heart disease that everyone can modify. Dr Stephen Kopecky, a cardiologist at the Mayo Clinic, discusses 4 ways to prevent a heart attack. You must 1-avoid smoking, 2-lower your BMI to <25, 3-eat 5 fruits and vegetables a day, 4-exercise. Taking Omega 3 fatty acids can also help.
64 slice CT scan to help diagnose coronary artery disease. The 64 Slice CT scan is essentially an angiogram of the heart arteries using cat scan. It is sometimes seen as the Heart Scan or Heart CT. It can be a helpful tool for cardiologists to diagnose coronary artery disease. This procedure can find blockages in the heart arteries, similar to a heart catheterization, but noninvasively.
Dr. Vance Plumb from the University of Alabama at Birmingham discusses the use of ablation for atrial fibrillation. Atrial Fibrillation is the most common heart arhythmia. It can cause symptoms such as fast heartbeat, irregular pulse, chest pain, shortness of breath, and dizziness. In an ablation, you find the electrical activity in the heart that is causing the abnormal rhythm, then use radiofrequency energy to burn that area.
Adults with congenital heart disease who underwent treatment for their congenital defect as they frequently have heart problems later in life. It is important for anyone who has undergone surgery to repair congenital defects to continue to see a cardiologist into adulthood. Heart arrhythmias are very common as are valve problems later in life. Dr. Keith Oken, a cardiologist from the Mayo Clinic, discusses adults with repaired congenital heart disease.
Atrial fibrillation is a rhythm abnormality in the top chamber of the heart which causes the top chamber to fibrillate, as opposed to having a normal coordinated contraction. The pulse will be irregular, and usually too fast. Symptoms can be fainting, or weakness, feeling an irregular heartbeat, palpitations. Afib can lead to blood clots, which may cause a stroke.
Aortic Coarctation. Aortic coarctation is a congenital narrowing of the Aorta- the major blood vessell of the body. IF left untreated, hypertension, stroke, heart disease are all more likely. A balloon catheter can be used to open the narrowing in aortic coarctation. Dr. William Moskowitz. VCU.
Aortic stenosis is a narrowing of the aortic valve, which is the valve between the heart and the aorta-the main blood vessel of the body. Symptoms of aortic stenosis include shortness of breath, leg swelling, chest pain, and syncope- or passing out, fainting. An echocardiogram or ultrasound of the heart confirms the diagnosis. Surgery is the traditional treatment for severe aortic stenosis, but valves done through catheters are being tested.
Aortic Valve Replacement. After the chest is opened and the heart exposed, you are put on the heart-lung bypass machine. Then the surgeon takes out you diseased valve, and is replaced with a prosthetic valve- either a mechanical valve, or a tissue valve-usually porcine. This is performed in patients with severe aortic stenosis, or narrowing of the aortic valve, or aortic regurgitation- leaking of the aortic valve. Video courtesy of eMedTV.com
Arrhythmias are abnormal heart rhythms. They may cause the heart to beat faster or slower than normal, making the heart less effective in pumping blood through the body. Some common cardiac arrhythmias are Bradycardia, Supraventricular Tachycardia, Atrial Fibrillation, Ventricular Fibrillation and Ventricular Tachycardia. To treat your arrhythmia your doctor may use one of or a combination of a variety of arrhythmia medications.
