The definition and clinical diagnostic criteria of metabolic syndrome (MS) are elaborated in this paper. The feature of left ventricular cardiac function changes of MS is identified through understanding of the relationships between hypertension, dyslipidemia, obesity, blood glucose abnormalities and left ventricular cardiac function. Decreased left ventricular function in patients with MS is caused by a number of cardiovascular risk factors, which lead to a number of complex metabolic reactions, affect the structure and metabolism of the myocardial environment and change the cardiac function and myocardial energy. Therefore, prior to development of symptomatic heart failure, MS patients may experience a period of subclinical left ventricular dysfunction.
