Hypercardia refers to hypertensive heart disease. The mechanism of hypertensive heart disease is due to the long-term poor control of hypertension, resulting in excessive cardiac afterload and changes in cardiac structure and function, including: early left ventricular diastolic hypoplasia, left ventricular hypertrophy (LVH), the gradual development of myocardial contractile hypoplasia and ultimately heart failure, and may be associated with coronary artery disease, atrial fibrillation and other cardiac comorbidities. Early manifestations of hypertensive heart disease are generally atypical, there may be no obvious symptoms or only mild discomfort such as headache, chest tightness and so on. In the progressive stage, precordial pain, chest tightness and shortness of breath, exertional angina, variant angina, transient syncope and blurred consciousness may occur. The diagnosis of hypertensive heart disease is based on a history of hypertension and hypertrophy or enlargement of the heart, and the thickness of the ventricular wall should be more than 12mm during the cardiac ultrasound examination. Treatment of hypertensive heart disease: Hypertensive heart disease is based on the premise of lowering blood pressure and requires antihypertensive treatment, such as: ARBs such as chlosartan and valsartan; ACEIs such as captopril; and beta-blockers such as propranolol. If similar symptoms occur, you should seek immediate medical attention and follow the doctor’s instructions to avoid delay.
