BackgroundThe independent prognostic impact of diabetes mellitus (DM) and prediabetes mellitus (pre‐DM) on survival outcomes in patients with chronic heart failure has been investigated in observational registries and randomized, clinical trials, but the results have been often inconclusive or conflicting. We examined the independent prognostic impact of DM and pre‐DM on survival outcomes in the GISSI‐HF (Gruppo Italiano per lo Studio della Sopravvivenza nella Insufficienza Cardiaca‐Heart Failure) trial.Methods and ResultsWe assessed the risk of all‐cause death and the composite of all‐cause death or cardiovascular hospitalization over a median follow‐up period of 3.9 years among the 6935 chronic heart failure participants of the GISSI‐HF trial, who were stratified by presence of DM (n=2852), pre‐DM (n=2013), and non‐DM (n=2070) at baseline. Compared with non‐DM patients, those with DM had remarkably higher incidence rates of all‐cause death (34.5% versus 24.6%) and the composite end point (63.6% versus 54.7%). Conversely, both event rates were similar between non‐DM patients and those with pre‐DM. Cox regression analysis showed that DM, but not pre‐DM, was associated with an increased risk of all‐cause death (adjusted hazard ratio, 1.43; 95% CI, 1.28–1.60) and of the composite end point (adjusted hazard ratio, 1.23; 95% CI, 1.13–1.32), independently of established risk factors. In the DM subgroup, higher hemoglobin A1c was also independently associated with increased risk of both study outcomes (all‐cause death: adjusted hazard ratio, 1.21; 95% CI, 1.02–1.43; and composite end point: adjusted hazard ratio, 1.14; 95% CI, 1.01–1.29, respectively).ConclusionsPresence of DM was independently associated with poor long‐term survival outcomes in patients with chronic heart failure.Clinical Trial Registration

Background—
We investigated the association between 9 polymorphisms of genes encoding hemostasis factors and myocardial infarction in a large sample of young patients chosen because they have less coronary atherosclerosis than older patients, and thus their disease is more likely to be related to a genetic predisposition to a prothrombotic state.
Methods and Results—
This nationwide case-control study involved 1210 patients who had survived a first myocardial infarction at an age of <45 years who underwent coronary arteriography in 125 coronary care units and 1210 healthy subjects matched for age, sex, and geographical origin. None of the 9 polymorphisms of genes encoding proteins involved in coagulation (G-455A β-fibrinogen: OR, 1.0; CI, 0.8 to 1.2; G1691A factor V: OR, 1.1; CI, 0.6 to 2.1; G20210A factor II: OR, 1.0; CI, 0.5 to 1.9; and G10976A factor VII: OR, 1.0; CI, 0.8 to 1.3), platelet function (C807T glycoprotein Ia: OR, 1.1; CI, 0.9 to 1.3; and C1565T glycoprotein IIIa: OR, 0.9; CI, 0.8 to 1.2), fibrinolysis (G185T factor XIII: OR, 1.2; CI, 0.9 to 1.6; and 4G/5G plasminogen activator inhibitor type 1: OR, 0.9; CI, 0.7 to 1.2), or homocysteine metabolism (C677T methylenetetrahydrofolate reductase: OR, 0.9; CI, 0.8 to 1.1) were associated with an increased or decreased risk of myocardial infarction.
Conclusions—
This study provides no evidence supporting an association between 9 polymorphisms of genes encoding proteins involved in hemostasis and the occurrence of premature myocardial infarction or protection against it.
The aim of the study was to compare the pulmonary effects of four beta-blockers with different ancillary properties: propranolol (non-beta 1 selective without ISA), oxprenolol (non-beta 1 selective with ISA), atenolol (beta 1 selective), and celipropol (beta 1 selective with mild beta 2-agonist and alpha 2-antagonist activity) in hypertensive patients with chronic obstructive lung disease. Ten asthmatic patients, all males, aged 50-66 years were studied. Entry criteria were a) DBP greater than or equal to 95 mmHg and less than or equal to 115 mmHg; b) FEV1 less than 70% of the theoretical values; c) FEV1 increase of at least 20% after salbutamol inhalation (200 micrograms). After a 2-week washout period on placebo, each patient received propranolol (80 mg/day), oxprenolol (80 mg/day), atenolol (100 mg/day), and celiprolol (200 mg/day) for 1 week, according to a randomized, cross-over design. At the end of the washout and of each treatment period, airway function, assessed by FEV1, FVC, and FEV1%, was evaluated by spirometry both in the basal condition and after salbutamol inhalation. Unlike propranolol and oxprenolol, which significantly reduced FEV1 and inhibited the bronchodilator response to inhaled salbutamol, atenolol and celiprolol did not significantly affect respiratory function and did not antagonize salbutamol effects. Celiprolol more closely approached placebo in its respiratory effects than did atenolol, although the differences were not statistically significant.
A randomized, double-blind, placebo controlled study evaluated the effects on 24 h ambulatory blood pressure (ABP) of isradipine sustained release (I-SRO) administered once daily, in the morning (AM) or in the evening (PM Hg after AM and 14.3/7.9 mm Hg after PM intake. No significant differences were detected in the BP lowering effect of the two I-SRO regimens. In hypertensive patients, isradipine sustained release 5 mg once daily given in the morning or in the evening is effective in reducing the 24 h blood pressure profile, irrespective of the time of administration.
