Heart failure (HF) and renal dysfunction are frequent associated in the same patient. The purpose of our study was to assess the prevalence of renal dysfunction and the clinical status in admitted patients for decompensated HF. Material and Methods. 397 patients succesively hospitalized for decompensated HF, NYHA III or IV functional class, with left ventricular ejection fraction (LVEF) � 45% were included in the study. Renal dysfunction was defined by glomerular filtration rate (GFR) [ 60 mL/min/1.73 m 2. The mean GFR in patients with HF was 63.89 � 21.5 mL/min/1.73 m2 .The prevalence of renal dysfunction was 49.6%. Patients with GFR [ 60 mL/min/1.73m2, compared with those with preserved renal function were significantly more frequent older (75.37 � 6.84 vs. 71.33 � 8.08 years; p [0.001), females (53,8% vs. 43.5%; p = 0.04), had a significantly higher prevalence of diabetes mellitus (50.2% vs. 28.5%; p [0.001), atrial fibrillation (53.8% vs 46.2%, p = 0.04) and anemia (47.7% vs. 29.5% ; p [0.001). Also, patients with renal dysfunction had more severe HF than those without renal dysfunction (NYHA class IV: 65% vs 45%, p [0.001, clinical congestion: 78.2% vs 68%, p = 0.02, LVEF [35%: 47.21% vs � 35%, p [0.001). Renal dysfunction can be considered an additional marker of severe cardiac dysfunction along with NYHA IV class and low LVEF. The presence of both renal dysfunction and anemia could represent prognostic markers in HF patients with reduced LVEF.
Accurate measurement of blood pressure (BP) and evaluation of global cardiovascular risk is crucial for diagnosis and treatment of hypertensive patients. When hypertension and diabetes mellitus are associated, the risk for cardiovascular events is bigger than the sum of the components. Beyond systolic and diastolic BP values as targets for antihypertensive treatment, recent guidelines recognize BP variability as an independent predictor for future cardiovascular events. 24 hours ambulatory BP monitoring (ABPM) and home BP monitoring (HBPM) are two methods used in patient day to day life conditions for BP measurements. Increased variability of systolic and/or diastolic BP within one day ("short-term BP variability") and also over longer periods ("long-term BP variability") showed by ABPM and/or HBPM is associated with target-organ damage and cardiovascular events. This review is focused on the prognostic importance of BP variability in hypertensive patients with diabetes mellitus.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
