New findings counsel that this beforehand neglected issue might play a extra vital function in coronary heart failure danger than beforehand thought.
Stomach fats linked to coronary heart failure danger
Analysis introduced on the American Coronary heart Affiliation’s 2026 Scientific Periods means that fats saved across the waist could also be extra strongly linked to coronary heart failure than general physique weight.
