Diffuse weakening of left ventricular wall motion is commonly seen in dilated cardiomyopathy, which should be prevented by removing the triggers of heart failure, preventing heart failure, and preventing complications in order to block myocardial damage.
1. Remove the triggers of heart failure, such as infection, arrhythmia, inappropriate application of antihypertensive drugs, too much and too fast infusion of fluids, emotional excitement, excessive physical labor and so on.
2. Treatment for heart failure: applying drugs to improve the prognosis of heart failure and reduce the death rate of heart failure, such as β-blockers (bisoprolol, metoprolol, etc.), angiotensinase inhibitors (valsartan, chlorosartan, etc.), aldosterone antagonists (spironolactone).
If there are symptoms of heart failure, symptom-improving drugs such as diuretics (furosemide, hydrochlorothiazide, etc.), cardiotonic agents (digitalis, etc.), and vasodilators (isosorbide nitrate, etc.) are applied.
The latest guideline proposes a new quadruple combination of drugs for heart failure, i.e., angiotensinase inhibitor/angiotensin receptor inhibitor/angiotensinase enkephalinase inhibitor, β-blocker, aldosterone antagonist combined with sodium-glucose cotransporter protein 2 inhibitor (dagliflozin, engeletin, etc.).
3. Prevention and treatment of complications: embolism is a common complication that requires long-term oral anticoagulants such as warfarin and rivaroxaban.
If diffuse weakening of left ventricular wall motion occurs, one should actively consult the hospital and ask the doctor to guide the treatment.
