Strong heart health lowers long-term death risk in cancer survivors

Higher Life’s Simple 7 cardiovascular health scores were associated with lower long-term all-cause and cancer mortality in cancer survivors from a large Italian cohort. Inflammation, resting heart rate, and vitamin D statistically explained a substantial share of these associations, supporting shared cardiometabolic pathways across cancer and cardiovascular disease.

Intermittent fasting edges daily calorie cuts for blood pressure and long-term cardiovascular risk estimates

In a real-world registry study of adults with overweight or obesity, 5:2 intermittent fasting and daily calorie restriction both improved blood pressure over 12 weeks. Intermittent fasting produced modestly greater reductions in systolic and pulse pressure and a larger drop in BMI-based 30-year cardiovascular risk scores, without superior lipid or glycaemic effects.
