Vitamin D is Related to Markers of Vulnerable Plaque in Acute Myocardial Infarction.

Background: Vitamin D is a fat soluble vitamin involved in calcium and bone metabolism; recently its deficiency has been related to cardiovascular disease. In cardiac tissue, vitamin D suppresses metalloproteinases (MMPs) expression, enzymes directly associated with vulnerable plaque.

Objective: To investigate whether the association between vitamin D and leptin is related to markers of vulnerable plaque, such as MMPs in patients with acute myocardial infarction.

Matrix metalloproteinases and psychosocial factors in acute coronary syndrome patients.

Unlabelled: Psychosocial factors have been linked to cardiovascular diseases independently of traditional risk factors. The impact of psychosocial factors on plaque destabilizing factors, such as matrix metalloproteinases (MMPs) has been proposed although scarcely studied.

Objective: To evaluate the relationships between hostility, perceived stress and social support with MMPs activity in patients after an Acute Myocardial Infarction (AMI).
