Does concentric left ventricular hypertrophy (LVH) progress to dilated cardiomyopathy (DCM)? It may not be as common as we previously thought and the transition may occur over decades.
1,386 participants of the Dallas Heart Study without baseline LV dilation were included. Ten percent of the participants had baseline LVH (7.2 g/mL0.67 for men and 5.8 g/mL0.67 for women). The study population had a mean age of 44 years, 57% women and 43% black patients. Of note, patients that developed cardiovascular disease during the study period (MI, CABG, PCI, stroke or HF) were not included in the final cohort of 1282. Baseline and follow up cardiac magnetic resonance imaging was performed a median of 7 years after baseline imaging.
