Paroxysmal nocturnal dyspnea (PND) You have trouble breathing while sleeping, which may cause you to wake up. Ongoing asthma, heart failure, pulmonary hypertension, or chronic obstructive pulmonary disease (COPD) may be the cause. Symptoms of acute left heart failure occur and include severe dyspnea even at rest, orthopnea, and PND. You have persistent shortness of breath lasting longer than 2-3 weeks. Heart disease also causes people to worry about their health. Other symptoms related to low cardiac output include fatigue, weakness and in extreme cases, cardiac cachexia can occur.Īlmost all patients with significant acute aortic regurgitation are symptomatic, unlike chronic aortic regurgitation. Paroxysmal nocturnal dyspnea (waking up from sleep feeling short of breath). Hepatic congestion can occur causing right upper quadrant abdominal pain. When the legs are elevated at night, the fluid redistributes centrally causing pulmonary edema resulting in orthopnea (dyspnea while laying flat) or paroxysmal nocturnal dyspnea (PND). The most common cause of right heart failure is left heart failure. Right heart failure symptoms include lower extremity dependant edema. Orthopnea occurs when pulmonary congestion causes the lungs to become stiff and non-compliant, which is when the lungs are unable to stretch and expand to. With physical activity the heart demands increased cardiac output which is not able to be met in states of heart failure and thus left heart pressures increase significantly causing this transient pulmonary edema.Īs those increased pressures from the left heart affect the right ventricle, right heart failure can ensue. The pressure increases in the left heart transmit to the lungs causing pulmonary edema and shortness of breath. ![]() Signs of left and right heart failure occur late in disease. Left heart failure results in symptoms related to the low cardiac output. Angina may occur in the absence of atherosclerotic coronary disease since the low diastolic pressures in severe aortic regurgitation compromise coronary filling and the LVH results in increased oxygen demand. Social and occupational history can reveal important clues as to possible causes. The first symptoms experienced may result from the large stroke volumes and forceful LV contractions causing the patient to experience palpitations. ![]() ![]() This results in patients remaining asymptomatic for a long period of time early in disease. The symptoms of aortic valve regurgitation are those predominately of congestive heart failure. As chronic aortic regurgitation develops slowly over time, the left ventricle can easily compensate slowly as described previously.
