Studies reported conflicting results on the effect of renin-angiotensin-aldosterone system (RAAS) blocker use on acute kidney injury (AKI) in patients undergoing elective coronary angiography but association in elderly patients with ST-elevation myocardial infarction (STEMI) is not known. Also, there are limited data on the effect of inflammatory markers on AKI. We aimed to investigate the effects of RAAS blocker pretreatment and inflammatory markers on AKI in this population. A total of 471 patients were compared according to presence of RAAS blocker pretreatment at admission. Conventional and inverse probability weighed conditional logistic regression were used to determine independent predictors of AKI. Mean age of the study group was 75.4 ± 7.1 years and 29.1% of the patients were female. AKI was observed in 17.2% of the study population. Weighted conditional multivariable logistic regression analysis revealed that AKI was associated with baseline creatinine levels and C-reactive protein/albumin ratio (CAR) (OR 2.08, 95% CI = 1.13–3.82, p = .02 and OR 1.19, 95% CI = 1.01–1.41, p = .04, respectively). No significant association was found between RAAS blocker pretreatment and AKI. CAR and elevated baseline creatinine levels were independent predictors of AKI in this patient group.

Objective: Lifelong statin treatment is recommended in patients with cardiovascular diseases, but drug adherence is a significant problem. The aim of this study was to investigate factors related to statin discontinuation in high-risk patients with coronary artery disease (CAD) diagnosed by coronary angiography. Methods: A total of 300 consecutive patients who were followed-up with a diagnosis of CAD were recruited. Patients were categorized as statin adherent or statin non-adherent (patients interrupting statin therapy >30 days). Study participants completed a questionnaire regarding demographic characteristics, medical history, knowledge of statin treatment, and factors related to statin discontinuation. Results: In all, 160 patients (53.3%) were found to be statin adherent. Of those, 122 patients had suffered myocardial infarction, and atorvastatin was the most prescribed statin on discharge. Among the study population, 26% were illiterate and 55% had graduated from primary school. Only 39 cases (13%) cases had a low-density lipoprotein-cholesterol level

Objectives: Previous studies have shown the association between various hematological parameters and cardiovascular diseases, and their prognostic value. In this study, we compared red cell distribution width (RDW), neutrophil lymphocyte ratio (NLR) and mean platelet volume (MPV) measurements among patients with poor coronary collateral circulation (CCC) and well-developed CCC. Study design: 326 patients with stable coronary artery disease (CAD) were evaluated retrospectively. CCC was graded by using the Rentrop classification. The poor CCC group included patients with Rentrop 0-1 CCC, and the good CCC group included Rentrop 2-3 CCC. Results: There were 171 subjects (84% male; mean age 56.6+-10.4 years) in the poor CCC group, and 155 subjects (89% male; mean age 57.6+-9.7 years) in the good CCC group. The total number of vessels with >95% stenosis (1.1+-0.5 vs. 1.0+-0.4; p=0.64) and Gensini scores (84.4+-38.8 vs. 83.3+-37.4; p=0.83) was not higher in the poor CCC group compared to the good CCC group. RDW was significantly higher in the poor CCC group compared to the good CCC group (14.19+-1.36% vs. 13.89+-1.19%; p=0.04). In multivariate logistic regression analysis, elevated levels of RDW and LDL were found to be independent predictors of poor CCC (OR 1.73, 95% CI: 1.30-2.29, p=0.01 and OR 1.01 95% CI 1.002-1.02; p=0.02, respectively). Conclusion: In the present study, poor CCC was found to be independently correlated with RDW, but not with any other hematological parameters in patients with stable CAD.

We present a 73-year-old male patient with an unusual complication of a broken coronary stent catheter during percutaneous coronary angioplasty, which was successfully retrieved by balloon trapping and pulling-back method, along with literature review of similar cases.
