Heart disease during pregnancy

Outlined a heart attack during pregnancy can be divided into two broad categories. The first category of pre-existing heart disease, rheumatic heart disease and congenital majority, hypertensive heart disease, Mitral valve prolapse and hypertrophic heart disease rare. The second category from pregnancy-induced heart disease, such as pregnancy-induced hypertension heart disease, heart perinatal period. A clinical performance. Heart failure : If the original heart patients have impaired heart function or barely compensated. Pregnancy may further decompensated heart failure. Pregnant women in rheumatic heart dysfunction as follows : ① lung disposable blood : more common in mitral valve disease, the patient short breath, tiredness after even more. both lungs base is small wetlands rales. X-ray examination of interstitial edema. ② acute pulmonary edema : more common in severe mitral stenosis, high blood volume increased pulmonary arterial pressure caused. Patients with sudden short breath, not recumbent, cough, cough bubble-like blood or sputum, scattered in both lungs wheezing or wet rales. ③ right heart failure : common in older age, heart expand more notable, atrial fibrillation, which are usually labor receded, or have a history of heart failure Treasury. CHD associated with pregnant women, patent ductus arteriosus, atrial septal defect, ventricular septal defect associated with pulmonary hypertension, often leads to right heart failure; pulmonary valve stenosis and tetralogy of Fallot, the right ventricular pressure overload. also display more of right heart failure; Aortic stenosis can be due to left ventricular pressure overload and the table left heart failure. 2. Infective endocarditis : Regardless of rheumatic heart disease or congenital heart disease can be complicated by bacteremia and infective endocarditis. If not controlled in time can trigger heart failure and death. 3. Cyanosis and hypoxia : cyanotic congenital heart disease in peacetime, and that is hypoxia cyanosis, pregnancy peripheral resistance low, increasing cyanosis. Non-cyanotic type, from left to right shunt CHD pregnant women, for some reason, such as loss of blood pressure decreases, they may call a temporary reverse triage, that the right-to-left shunt, which led to cyanosis and hypoxia. 4. Embolization : During pregnancy, blood in the hypercoagulable state, and heart disease associated with the increased venous pressure and venous blood stagnation. easily with thrombosis. Likely to come from the pelvic thrombosis, pulmonary embolism caused, increased pressure on the pulmonary circulation, thereby stimulating pulmonary edema, or left to right shunt reversed to the right-to-left shunt. If the cavity of the heart about the traffic congenital heart disease, thrombosis may defect caused by peripheral arterial embolization. If diagnosed before pregnancy is aware that with organic heart disease, the diagnosis does not exist, of course, However, some patients without symptoms may not seek medical treatment. Pregnancy caused by the series of the cardiovascular system function can lead to heart palpitations, short breath and symptoms such as edema, can be accompanied by increased heart mild heart murmur and signs such as X-ray, electrocardiogram, thereby increasing cardiac diagnosis difficult. However, if the following anomalies, should consider the existence of organic heart disease. 1. III level and above, the rough systolic murmur. 2. Diastolic murmur. 3. Serious arrhythmia, such as atrial fibrillation or flutter, including atrioventricular block. 4.X ray said cardiac expanded significantly, particularly individual atrial or ventricular expanded significantly. 5. Echocardiography revealed heart valve, atrial and ventricular lesions.
