Cardiovascular Research: Common mutation linked to heart disease ♦ Faster heart rate linked to diabetes risk ♦ Depression associated with risk of heart failure

Common mutation linked to heart disease A common mutation in a gene that regulates cholesterol levels may raise the risk of heart disease in carriers up to 49 percent, particularly among men and African Americans.
Faster heart rate linked to diabetes risk An association between resting heart rate and diabetes suggests that heart rate measures could identify individuals with a higher future risk of diabetes.
Obesity, mood disorders increase peripartum cardiomyopathy risk Anxiety, depression and bipolar disorder doubles the risk of peripartum cardiomyopathy during childbirth, while obesity leads to a 1.7-fold increase, researchers report. Women with common pregnancy-related symptoms such as shortness of breath and leg swelling plus five PPCM risk factors could benefit from screening.
Depression associated with 5-fold increased mortality risk in heart failure patients Moderate to severe depression is associated with a 5-fold increased risk of all cause mortality in patients with heart failure, according to research. The results show that risk was independent of comorbidities and severity of heart failure. Patients who were not depressed had an 80% lower mortality risk.
