Heart failure (HF) is one of the most common causes of hospital admission and readmission in patients over 65 years of age. It is a clinical syndrome resulting from structural and functional cardiac disorders that impair the heart's ability to fill with (diastolic) and/or to eject (systolic) blood commensurate with the metabolic needs of the body. 1-3 A common precursor and contributor to HF is cardiac hypertrophy, a pathological condition that sets in as the heart attempts to compensate for its poor ability to circulate the blood. Cardiac hypertrophy is characterized by an increase in the size of individual cardiomyocytes, rather than their overall numbers, in order to temporarily maintain the cardiac output. 4 Long-term hypertrophy eventually leads to ischaemia, arrhythmia, heart failure and sudden death. 5 However, the precise pathophysiological mechanisms that explain the transition from hypertrophy to clinical HF are not well understood. 6
