In addition, high-quality evidence suggested that for patients with DCM, drugs such as atorvastatin, carvedilol, thyroid hormone, and L-carnitine could significantly improve LVEF and cardiac output and reduce C-reactive protein levels, systolic blood pressure, LVEDD, and left ventricular end-diastolic and end-systolic volumes. Here, TG is linked to familial dilated cardiomyopathy.
