Hypertrophic cardiomyopathy is a serious disease that affects the muscles of the heart. This leads to the thickening of the heart chambers (particularly the ventricles), stiffness of the left ventricles, and problems with the mitral valve(the valve between the left atriumand left ventricle). There...

Dietary fibre has emerged as a modulator of the gut microbiota, resulting in the release of gut metabolites called short-chain fatty acids (SCFAs), such as acetate. We have shown previously that fibre or acetate can protect against hypertension and heart disease in certain models. HF is also ...
