Both type 2 diabetes mellitus (DM2) and left ventricular hypertrophy are associated with an increased risk of cardiovascular diseases (CVD). A strong association between hyperinsulinemia, which is the hallmark of DM2 and of insulin resistance syndrome (a cohort of metabolic abnormalities such as DM2, dyslipidemia, hyperuricemia, obesity, hypertension, hyperfibrinogenemia), and left ventricular (LV) hypertrophy was found in several studies. We studied 140 consecutive (both normo- and hypertensive) DM2 patients to determine a possible link between metabolic features and the degree of LV mass, calculated by the ECG method of Cornell voltage. The Cornell voltage value was 12.9 +/- 0.5 mm in the DM2 population as a whole, and 13.6 +/- 0.7 vs 11.7 +/- 0.9 mm (p=NS) in hypertensive and normotensive DM2 subgroups, respectively. Among all the metabolic parameters taken into account, the multivariate analysis shows that the fasting plasma insulin level is the strongest independent predictor of LV mass, both in the whole population (p=0.0005) and in the normo (p=0.0460) and hypertensive DM2 (p=0.0184) subgroups

Abstract
Both type 2 diabetes mellitus (DM2) and left ventricular hypertrophy are associated with an increased risk of cardiovascular diseases (CVD). A strong association between hyperinsulinemia, which is the hallmark of DM2 and of insulin resistance syndrome (a cohort of metabolic abnormalities such as DM2, dyslipidemia, hyperuricemia, obesity, hypertension, hyperfibrinogenemia), and left ventricular (LV) hypertrophy was found in several studies. We studied 140 consecutive (both normo- and hypertensive) DM2 patients to determine a possible link between metabolic features and the degree of LV mass, calculated by the ECG method of Cornell voltage. The Cornell voltage value was 12.9 +/- 0.5 mm in the DM2 population as a whole, and 13.6 +/- 0.7 vs 11.7 +/- 0.9 mm (p=NS) in hypertensive and normotensive DM2 subgroups, respectively. Among all the metabolic parameters taken into account, the multivariate analysis shows that the fasting plasma insulin level is the strongest independent predictor of LV mass, both in the whole population (p=0.0005) and in the normo (p=0.0460) and hypertensive DM2 (p=0.0184) subgroupsI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
