Background:
- Pathological cardiac hypertrophy is a heart response to stimuli like aging, ischemia, and hypertension.
- Prolonged stress can lead to heart failure.
- Autophagy is a vital cellular process for maintaining homeostasis.
Purpose of the Study:
- To review recent advancements in understanding autophagy's function in cardiac hypertrophy.
- To discuss therapeutic strategies targeting autophagy for cardiac hypertrophy.
Main Methods:
- Literature review of recent scientific progress.
- Analysis of the role of cardiomyocyte autophagy in cardiac hypertrophy.
Main Results:
- Autophagy is tightly linked to cardiac hypertrophy.
- Regulated autophagy protects the heart from various stimuli by clearing cellular waste.

- Targeting autophagy presents a promising therapeutic avenue for treating cardiac hypertrophy and preventing heart failure.
Abstract:
Pathological cardiac hypertrophy is the response of heart to various biomechanical and physiopathological stimuli, such as aging, myocardial ischemia and hypertension. However, a long-term exposure to the stress makes heart progress to heart failure. Autophagy is a dynamic self-degradative process necessary for the maintenance of cellular homeostasis. Accumulating evidence has revealed a tight link between cardiomyocyte autophagy and cardiac hypertrophy. Sophisticatedly regulated autophagy protects heart from various physiological and pathological stimuli by degradating and recycling of protein aggregates, lipid drops, or organelles. Here we review the recent progresses concerning the functions of autophagy in cardiac hypertrophy induced by various hypertrophic stimuli. Moreover, the therapeutic strategies targeting autophagy for cardiac hypertrophy will also be discussed.
