Electrocardiographic abnormalities of left ventricular repolarization: Prognostic implications in hypertensive post-menopausal women
چکیده انگلیسی

BackgroundAlthough repolarization abnormalities on ECG are frequent in post-menopausal hypertensive women, their prognostic value in these women is uncertain.MethodsWe analyzed 908 hypertensive post-menopausal women consecutively included in the PIUMA (Progetto Ipertensione Umbria Monitoraggio Ambulatoriale) study. The median duration of follow-up was 8.6 years (range: 1–21). All women were untreated at entry. Drug treatment during follow-up was adjusted to single individuals. Standard 12-lead ECG was carried out at entry. The Minnesota Coding was used to define minor and major (“typical strain”) repolarization abnormalities.Designprospective observational study in essential hypertension.ResultsMean age at entry was 60 years. At baseline, ECG was normal in 707 women, minor ST-T changes were noted in 152 women, and a typical strain pattern was present in 49 subjects. Predictors of typical strain were age, diabetes and systolic blood pressure (BP). During follow-up there were 119 new cardiovascular (CV) events and 75 all-cause deaths. Typical strain was associated with a threefold higher risk of CV disease (HR: 3.16; 95% CI: 1.59–6.31; p = 0.001) after adjustment for the significant influence of age, diabetes, serum creatinine, systolic BP and HDL-cholesterol. Women with minor LV repolarization abnormalities showed a non-significant excess risk of CV disease when compared with women with normal LV repolarization (HR: 1.25; 95% CI: 0.69–2.26; p = 0.467). Similar results were obtained for all-cause mortality.ConclusionsTypical strain pattern, an easily detectable marker of altered LV repolarization, identifies post-menopausal hypertensive women at increased risk of CV disease and all-cause mortality.
