Relationship between obstructive sleep apnea and coronary microcirculatory function among patients with cardiac syndrome X.
Obstructive sleep apnea (OSA) is an emerging risk factor for cardiovascular disease. Microcirculatory dysfunction has been proposed as a potential mechanism in the pathogenesis of cardiovascular disease in OSA. This study aims to investigate the relationship between OSA and coronary microcirculatory function. ⋯ As compared with having no sleep apnea, categories with higher AHI were associated with increased odds of lower coronary flow reserve. The data suggested a close relationship between OSA and coronary microcirculatory function in atherosclerosis.

Observational StudyPrognostic impact of anaemia on patients with ST-elevation myocardial infarction treated by primary PCI.
The aim of this study was to investigate the effects of baseline anaemia on the outcome in patients treated by primary percutaneous coronary intervention (PPCI) for ST-elevation myocardial infarction. ⋯ Patients with anaemia undergoing PPCI are at a higher risk of an adverse outcome. Anaemia is a simple and powerful marker of poor prognosis. Although anaemia (based on the WHO definitions) does not appear to be an independent predictor of all-cause mortality or major adverse cardiac events after PPCI on multivariate analysis, there appears to be a threshold value of Hb among men, below which there is an associated increased risk for PPCI.

Comparative StudyQuality of life 12 years after on-pump and off-pump coronary artery bypass grafting.
To assess whether the use of either the on-pump or the off-pump method affects changes in health-related quality of life (QOL) in the long term after coronary artery bypass graft (CABG) surgery. ⋯ A majority of patients experience significant improvement in health-related QOL in the long term after CABG. Cardiopulmonary bypass has no impact on patients' subsequent health-related QOL.

Multicenter Study Observational StudyPrevalence and prognosis of congestive heart failure in Saudi patients admitted with acute coronary syndrome (from SPACE registry).
The aim of this study was to assess the prevalence, clinical features, and in-hospital outcomes of heart failure in patients with acute coronary syndrome (ACS). ⋯ ACS patients with CHF in the Saudi Project for Assessment of Coronary Events were older, more likely to have more cardiac risk factors, and less likely to be treated with optimum medical treatment on admission. These findings were associated with higher incidence of their in-hospital adverse outcomes. More aggressive treatment is warranted to improve prognosis.

Comparative Study Observational StudyLong-term effectiveness and safety of triple versus dual antiplatelet therapy after percutaneous coronary intervention for unprotected left main coronary artery disease.
We sought to compare the long-term effectiveness and safety of triple antiplatelet therapy (TAPT) versus dual antiplatelet therapy (DAPT) after percutaneous coronary intervention (PCI) for unprotected left main coronary artery disease (uLMCAD). ⋯ TAPT after drug-eluting stent implantation in patients with uLMCAD did not improve the long-term clinical outcome when compared with conventional DAPT, although it was a safe strategy.
