Left ventricular diastolic dysfunction

Introduction Left ventricular diastolic dysfunction is closely related to the elderly, and diastolic dysfunction is also caused by long-term myocardial ischemia. Diastolic dysfunction plays a major role in the symptoms and signs of heart failure, accounting for approximately 40% of patients with congestive heart failure (CHF).

Cause

Causes of left ventricular diastolic dysfunction in the heart:

1, aging changes, cardiac function has declined slightly;

2, caused by myocardial ischemia, the majority of young people are more common in myocarditis, myocardial damage, high blood pressure and so on.

High blood pressure, myocardial ischemia, left ventricular hypertrophy, or the appearance of vascular stenosis or embolism.

1. Electrocardiogram examination: 1. The inner diameter of the left atrium is not thickened, the left internal diameter is not increased, the wall of the chamber is not thickened, and no abnormality of the wall motion is observed in the resting state; 2. The mitral valve is not thickened and developed. Unrestricted; CDFI; slight reflux; 3. Ascending aorta does not widen, aortic valve trifoliate, development is not limited; CDFI: slight abnormality; 4. Right atrial diameter does not increase, right internal diameter does not increase , the pulmonary artery does not widen; CDFI; slight tricuspid regurgitation; pulmonary valve without anti-retention.

Second, left ventricular diastolic function: mitral valve blood flow map: VA> VE; pulmonary artery blood flow map: AR deep and wide, SD2.

Differential diagnosis

Differential diagnosis:

Tricuspid regurgitation: severer may have fatigue, poor appetite, liver pain, abdominal swelling and lower extremity edema, jugular vein engorgement with pulsation, hepatomegaly and sputum and pulsation; and sternal left margin 4 The systolic squeaky sound of the ribs during the full systole, the murmur is enhanced at the end of deep inhalation (Carvallo sign).
