Echocardiography shows decreased left ventricular wall motion.

Under normal circumstances, left ventricular wall motion refers to the inward movement of the left ventricular myocardium. Weakening of this inward motion may be associated with conditions such as hypertension, viral myocarditis, cardiomyopathy, pericardial effusion or constriction, and myocardial ischemia. The specific causes are analyzed as follows:

1. Hypertension

Hypertension primarily increases the load on the left ventricular wall, leading to myocardial cell hypertrophy and fibrosis, which in turn affects myocardial contractile function. Patients are advised to follow medical guidance and use medications such as propranolol hydrochloride tablets and nicardipine hydrochloride tablets for treatment.

2. Viral Myocarditis

Viral infection can cause localized or diffuse myocarditis. When the virus severely damages left ventricular myocardial cells, these cells may fail to maintain normal function, resulting in weakened inward motion of the left ventricular myocardium. Patients are advised to follow medical guidance and use medications such as human interferon α2b suppositories and ribavirin tablets for treatment.

3. Cardiomyopathy

Certain types of cardiomyopathy, such as dilated cardiomyopathy and hypertrophic cardiomyopathy, can also lead to reduced inward motion of the left ventricular myocardium. These conditions may involve abnormal proliferation, fibrosis, or remodeling of myocardial cells, resulting in decreased myocardial contractility. Patients are advised to follow medical guidance and use medications such as losartan potassium hydrochlorothiazide tablets and metoprolol tartrate tablets for treatment.

4. Pericardial Effusion or Constriction

Pericardial effusion or constriction refers to increased fluid between the pericardial layers or hardening of the pericardial membrane, which restricts cardiac diastole and systole, thereby affecting left ventricular wall motion. In such cases, the heart cannot fully expand or contract, leading to weakened inward motion. Patients are advised to follow medical guidance and use medications such as enteric-coated aspirin tablets and furosemide tablets for treatment.

5. Myocardial Ischemia

Myocardial ischemia is a common cause of weakened inward motion of the left ventricular myocardium. When ischemia occurs, myocardial cells become damaged or even die, reducing contractile strength and impairing left ventricular wall motion. Patients are advised to follow medical guidance and use medications such as nitroglycerin tablets and isosorbide mononitrate capsules for treatment.

Patients are advised to seek timely medical attention if discomfort occurs and to undergo standardized treatment under a physician's guidance, which helps promote recovery.
