The molecular mechanisms involved in the transition of cardiac hypertrophy to heart failure (HF) are not fully characterized. Autophagy is a catabolic, self‐renewal intracellular mechanism, which protects the heart during HF. In the heart of a mouse model of angiotensin‐II‐induced hypertrophy, Sun and colleagues demonstrated that reduced levels of miR‐93 lead to synaptotagmin‐7 (Syt‐7) upregulation and consequent inhibition of autophagy. miR‐93 overexpression or syt‐7 inhibition rescues autophagy and maladaptive hypertrophy. This research identifies new players in the pathophysiology of cardiac hypertrophy, opening innovative therapeutic perspectives. miR‐93 may also be considered in the future as a novel circulating biomarker for patients at high risk to develop HF.
