How Does Presyncope Relate To Heart Failure
Several causes: Presyncope which is the sensation that you might faint but actually do not lose consciousness. This sensation could be due to rapid changes in position like standing up. It may be due to low blood pressure due to diuretics or other meds. A change in heart rhythm (too slow or too fast) can also cause this feeling. Less commonly very poor pumping power can cause this sensation. ...Read moreSee 1 more doctor answer
Heart failure is a complex set of conditions in which the heart "fails" to pump a normal amount of blood with each beat. This can be due to poor squeezing function (systolic heart failure) and/or a stiff heart incapable of filling normally (diastolic heart failure). Common symptoms include swelling and trouble breathing, particularly when ...Read more
Weak heart muscle: A weakening of the heart muscle from coronary artery disease, too much alcohol or a viral infection weakens the heart muscle leading to chf. Find the cause first, then the treatment follows. See a good cardiologist, plenty of good ones in palo alto. ...Read moreSee 1 more doctor answer
Left heart failure: Left ventricle is the main pumping chamber of the heart and damage to that chamber either from a heart attack or a cardiomyopathy can lead to heart failure. Congestive heart failure is a condition where the heart cannot pump the blood delivered to it and backs up into the lungs causing shortness of breath. This can be caused by left heart failure, and can also lead to both chambers failing. ...Read more
High flow: The high blood flow of the hyperthyroid heart can cause all sorts of sounds, including murmurs. These may go away simply by slowing things down with a b-blocker, or by treating the thyroid. But other conditions can coexist, so talk to your doctor about whether or not an echocardiogram should be done. ...Read more
HF or angina: Angina is heart pain because not enough blood flow. This occurs with exertion, left sided pain that can radiate down left arm or to jaw. Heart failure symptoms come from fluid retention. There may be swelling in legs. Both cause shortness if breath, but in hf this is worse lying down. Chest pain in heart failure is fluid in the lungs a lot of the time. ...Read moreSee 1 more doctor answer
Vaso vagal syncope : Not really . Actually most ppl with this condition have structurally normal cardiac function that is not harmed by this condition. ...Read more
Anesthesia: Propofol is an anesthesia. It goes to the brain, and depresses the breathing center. This causes hypoxia to all tissues including the heart. The hypoxia also causes acidosis from anaerobic respiration, and vasodilatation and drop in bp. This all lead to hypoxia of tissues including heart muscles, and eventual death of tissues. ...Read more
All increase: Exercise causes an increased demand for blood flow to provide oxygen to the muscles doing the work. This is accomplished by increase in heart rate and stoke volume. Since cardiac output is determined by heart rate and stroke volume, it also goes up. Blood pressure also typically increases with strenuous exercise. ...Read more
Does heart failure always happen after a heart attack? What are the symptoms of heart failure and does heart attacks always lead to heart failure?
Heart : Heart failure can cause shortness of breath, which may worsen with activity or when lying down or sleeping. Heart failure can also cause chest pain, fatigue, exercise intolerance, swelling of the legs, abdominal fullness, loss of appetite, weight gain, or heart palpitations. The symptoms are related to water retention and decreased ability for the heart to maintain adequate blood flow to the body's vital organs. Heart attacks are the most common cause of heart failure, but they do not always lead to heart failure. In the modern era, there are several ways to treat heart attacks which minimize the risk of developing heart failure later. If you have had a heart attack, it is crucial to improve your risk factors to help prevent more heart attacks or the development of heart failure. This means eating healthy, exercising, not smoking tobacco, and controlling your blood pressure and cholesterol. ...Read moreSee 1 more doctor answer
One canlead to other: Hypertension can cause changes in the heart like overgrowth of the heart muscle or weakening of the muscle through plaque build up in the arteries that feed the heart or degradation of the heart valves. These changes can then cause the pump to fail, and when it doesn't pump well, fluid tends to build up in places like the lungs and we call that congestive heart failure. ...Read moreSee 1 more doctor answer
Many ways: Catecholamines (Adrenaline) can increase blood pressure, or act directly on the hearts nervous system to cause palpitations/raise heart rate. Artificial catecholamines mimic exercise/stress and can increase the demands on the heart. Thus, caution must be taken in someone who has heart disease. Exercise can prevent heart disease, but may need primary doctor evaluation before starting program. ...Read more
Depends...: There are heart rhythmn disorders that do not begin with an elevated heart rate. Not all cardiac arrhythmias are due to an elevated heart rate. There are rhythmn disorders that have a normal heart rate or even a slow heart rate. A normal or slow heart rate does not rule put an arrhythmia. ...Read moreSee 2 more doctor answers
SA node; slow heart: The sino-atrial (sa) node near the top of your right atrium is the natural pacemaker of the heart. A pacemaker is necessary if the native heart beat is so slow that you cannot maintain a normal blood pressure. Generally, a pulse of 60 or greater is needed to maintain a normal blood pressure, although some athletes can have lower heart rates. ...Read moreSee 1 more doctor answer
