Motivated patients showed significant improvements in smoking cessation and total cholesterol levels, as well as higher health-related quality of life.
A new study demonstrates that lowering LDL cholesterol and systolic blood pressure can have independent, multiplicative, and cumulative causal effects on cardiovascular disease risk. By reducing both by modest amounts, individuals may see a significant reduction in their lifetime risk of cardiovascular disease.
The new guidelines recommend individual LDL cholesterol targets based on risk, aiming for at least 50% reduction. Lifestyle and nutrition are emphasized, with goals for body mass index and food preferences.
A Johns Hopkins study of over 13,000 participants found that severe obesity is a standalone high-risk factor for heart failure, but not other types of heart disease. Morbidly obese individuals were nearly fourfold more likely to develop heart failure even after controlling for risk factors such as high blood pressure and diabetes.
A large-scale study found that both high and low levels of HDL cholesterol are associated with an increased risk of premature death. Intermediate levels, however, may increase longevity. The research used data from over 1.7 million male veterans and showed a U-shaped curve relationship between HDL cholesterol levels and mortality.
