Among dialysis patients, only 23% have a normal echocardiogram, about 10% have recurrent or chronic congestive heart failure, and 17% have asymptomatic ischemic heart disease. The predisposing factors for congestive heart failure are dilated cardiomyopathy, hypertrophic hyperkinetic disease, and ischemic heart disease. Dilated cardiomyopathy, a disorder of systolic function, includes among its risk factors age, hyperparathyroidism, and smoking. Hypertrophic disease results in diastolic dysfunction, and its predictors include age, hypertension, aluminum accumulation, anemia, and, perhaps, hyperparathyroidism. Ischemic heart disease is due to the presence of coronary artery disease and also to nonatherosclerotic disease caused by the reduction in coronary vasodilator reserve and altered myocardial oxygen delivery and use. The clinical outcome of congestive heart failure is comparable to that of nonrenal patients with medically refractory heart failure. Left ventricular hypertrophy is an important independent determinant of survival. A subset have hyperkinetic disease with severe hypertrophy and have a bad survival, as low as 43% have a 2-yr survival after the first admission to hospital with cardiac failure. The prognosis for those with dilated cardiomyopathy is less severe but is worse than those with normal echocardiogram. The survival of patients with symptomatic ischemic heart disease was little different from that of patients without symptoms, suggesting that the underlying cardiomyopathies had an adverse impact on survival independent of ischemic disease. Much research needs to be undertaken on the risk factors, natural history, and therapy of the various types of cardiac disease prevalent in dialysis patients.

In this article elucidated the influence of allelic polymorphism of Gln27Glu of β2-adrenoceptors gene on patients that have coronary heart disease and obesity on the expansion and progression of congestive heart failure and left ventricular systolic dysfunction by surveying 222 patients. Presence of C allel of polymorphous locus Gln27Glu of β2-adrenoreceptors gene in patients with ischemic heart disease and concomitant obesity was associated with decreased risk of development of congestive heart failure (p < 0.05). The obtained data shown the absence of influence of polymorphous variants of β2-adrenoreceptors gene on progression of congestive heart failure in patients with ischemic heart disease and obesity (p > 0.05).

Left bundle branch block is not a benign pathology, and its presence requires the identification of a pathological substrate, such as ischemic heart disease. Left bundle branch block appears to be more commonly associated with normal coronary arteries, especially in women. The objectives of our study were to describe the particularities of left bundle branch block in women compared to men with ischemic heart disease. Result: We included seventy patients with left bundle branch block and ischemic heart disease, with a mean age of 67.01 ± 8.89 years. There were no differences in the profile of risk factors, except for smoking and uric acid. The ventricular depolarization (QRS) duration was longer in men than women (136.86 ± 8.32 vs. 132.57 ± 9.19 msec; p = 0.018) and also men were observed to have larger left ventricular diameters. Left bundle branch block duration was directly associated with ventricular diameters and indirectly associated with left ventricular ejection fraction value, especially in women (R = −0.52, p = 0.0012 vs. R = −0.50, p = 0.002). In angiography, 80% of women had normal epicardial arteries compared with 65.7% of men; all these patients presented with microvascular dysfunction. Conclusion: The differences between the sexes were not so obvious in terms of the presence of risk factors; instead, there were differences in electrocardiographic, echocardiographic, and angiographic aspects. Left bundle branch block appears to be a marker of microvascular angina and systolic dysfunction, especially in women.

Background: Revascularization is often performed in patients with stable ischemic heart disease. However, whether revascularization reduces death and other cardiovascular outcomes is uncertain. Methods: We conducted PUBMED/EMBASE/Cochrane Central Register of Controlled Trials searches for randomized trials comparing routine revascularization versus an initial conservative strategy in patients with stable ischemic heart disease. The primary outcome was death. Secondary outcomes were cardiovascular death, myocardial infarction (MI), heart failure, stroke, unstable angina, and freedom from angina. Trials were stratified by percent stent use and by percent statin use to evaluate outcomes in contemporary trials. Results: Fourteen randomized clinical trials that enrolled 14 877 patients followed up for a weighted mean of 4.5 years with 64 678 patient-years of follow-up fulfilled our inclusion criteria. Most trials enrolled patients with preserved left ventricular systolic function and low symptom burden, and excluded patients with left main disease. Revascularization compared with medical therapy alone was not associated with a reduced risk of death (relative risk [RR], 0.99 [95% CI, 0.90–1.09]). Trial sequential analysis showed that the cumulative z-curve crossed the futility boundary, indicating firm evidence for lack of a 10% or greater reduction in death. Revascularization was associated with a reduced nonprocedural MI (RR, 0.76 [95% CI, 0.67–0.85]) but also with increased procedural MI (RR, 2.48 [95% CI, 1.86–3.31]) with no difference in overall MI (RR, 0.93 [95% CI, 0.83–1.03]). A significant reduction in unstable angina (RR, 0.64 [95% CI, 0.45–0.92]) and increase in freedom from angina (RR, 1.10 [95% CI, 1.05–1.15]) was also observed with revascularization. There were no treatment-related differences in the risk of heart failure or stroke. Conclusions: In patients with stable ischemic heart disease, routine revascularization was not associated with improved survival but was associated with a lower risk of nonprocedural MI and unstable angina with greater freedom from angina at the expense of higher rates of procedural MI. Longer-term follow-up of trials is needed to assess whether reduction in these nonfatal spontaneous events improves long-term survival.
