what is the most common cause of right ventricular heart failure
left-sided heart failure pulmonary heart disease
title: Heart failure text: tend to progress to failure of both ventricles. For example, left ventricular failure allows pulmonary edema and pulmonary hypertension to occur, which increase stress on the right ventricle. Right ventricular failure is not as deleterious to the other side, but neither is it harmless. Heart failure may also occur in situations of "high output" (termed "high-output heart failure"), where the amount of blood pumped is more than typical and the heart is unable to keep up. This can occur in overload situations (blood or serum infusions), kidney diseases, chronic severe anemia, beriberi (vitamin B/thiamine deficiency), hyperthyroidism, cirrhosis, Paget's disease, multiple title: Heart failure text: as dizziness, confusion and cool extremities at rest. Right-sided heart failure is often caused by pulmonary heart disease (cor pulmonale), which is typically caused by difficulties of the pulmonary circulation, such as pulmonary hypertension or pulmonic stenosis. Physical examination may reveal pitting peripheral edema, ascites, and liver enlargement. Jugular venous pressure is frequently assessed as a marker of fluid status, which can be accentuated by eliciting hepatojugular reflux. If the right ventricular pressure is increased, a parasternal heave may be present, signifying the compensatory increase in contraction strength. "Backward" failure of the right ventricle leads to congestion of systemic capillaries. title: Heart failure text: is not exclusively "backward failure" (in the part of the circulation which drains to the ventricle). There are several other exceptions to a simple left-right division of heart failure symptoms. Additionally, the most common cause of right-sided heart failure is left-sided heart failure. The result is that patients commonly present with both sets of signs and symptoms. The left side of the heart is responsible for receiving oxygen-rich blood from the lungs and pumping it forward to the systemic circulation (the rest of the body except for the pulmonary circulation). Failure of the left side of the heart causes blood title: Myocardial infarction complications text: a state called heart failure. There are different types of heart failure; left- or right-sided (or bilateral) heart failure may occur depending on the affected part of the heart, and it is a low-output type of failure. If one of the heart valves is affected, this may cause dysfunction, such as mitral regurgitation in the case of left-sided coronary occlusion that disrupts the blood supply of the papillary muscles. The incidence of heart failure is particularly high in patients with diabetes and requires special management strategies. Myocardial rupture is most common three to five days after myocardial infarction, commonly of title: Heart failure text: infarction (heart attack), high blood pressure, atrial fibrillation, valvular heart disease, excess alcohol use, infection, and cardiomyopathy of an unknown cause. These cause heart failure by changing either the structure or the functioning of the heart. The two types of heart failure - "heart failure with reduced ejection fraction" (HFrEF), and "heart failure with preserved ejection fraction" (HFpEF) - are based on whether the ability of the left ventricle to contract is affected, or the heart's ability to relax. The severity of disease is graded by the severity of symptoms with exercise. Heart failure is not the same as myocardial
