Left ventricular hypertrophy can generally be categorized as mild, moderate and severe. Mild left ventricular hypertrophy patients generally do not show obvious clinical symptoms, because the heart has a compensatory function; moderate left ventricular hypertrophy patients may show mild clinical symptoms, such as mild chest tightness and shortness of breath; patients with severe left ventricular hypertrophy, the degree of which has far exceeded the compensatory function of the heart, which will show obvious clinical symptoms, such as severe respiratory distress. Clinically, there are many reasons that can cause left ventricular hypertrophy, such as hypertension, coronary heart disease, for patients with left ventricular hypertrophy, need to clarify the causes of left ventricular hypertrophy as soon as possible, and timely treatment, otherwise long-term left ventricular hypertrophy is likely to affect the heart’s normal ejection function, and ultimately develop into irreversible heart failure. In terms of treatment, patients are advised to choose cardiotonic, diuretic and vasodilator drugs. In addition, during the treatment period, patients are advised not to overwork and to pay attention to more rest.
