Introduction: Despite high technical success of rescue Percutaneous Coronary Intervention (PCI) and also its significant impact on left ventricular function, the therapeutic outcome of this PCI technique in comparison with primary PCI for coronary reperfusion has remained uncertain. The present study aimed to conduct a comparative analysis of early and long-term results of patients with ST-Elevation Myocardial Infarction (STEMI), who had undergone primary or rescue PCI.Methods: One hundred and twenty-nine consecutive patients with the diagnosis of STEMI, who underwent primary PCI (n = 107) or rescue PCI (n = 22) from April 2012 to September 2013 were retrospectively included. In addition to early assessment of procedural consequences, the patients were followed-up to assess and compare long-term mortality and major adverse cardiovascular events.Results: Comparing in-hospital consequences of the two rescue PCI and primary PCI procedures showed no significant differences in in-hospital mortality (9.5% vs. 3.7%, P = 0.255), total hospital stay (6.32 Â± 2.24 days vs. 6.61 Â± 3.43 days, P = 0.720) and also in early procedural complications. Long-term death was found only in 1.9% of patients in the primary group and none of the patients in the rescue group (P = 0.999). There was also no difference in the prevalence of late stent thrombosis between the two groups. However, the in-hospital Left Ventricular Ejection Fraction (LVEF) was lower in the rescue PCI group vs. primary PCI group (36.82 Â± 11.19 vs. 43.48 Â± 9.14, P = 0.014), but after six months, LVEF was similar between the two groups (41.05 Â± 9.57 vs. 44.29 Â± 10.35, P = 0.082).Conclusions: Our study showed no difference in early and late procedural outcome between the primary and rescue PCI techniques in STEMI patients, but LVEF had better improvement in the rescue PCI group.

Introduction: N-terminal pro-B-type natriuretic peptide (NT-proBNP) has emerged as an important biomarker for developing the diagnosis and prognosis of cardiovascular diseases, as several studies have shown that serum levels of NT-proBNP elevate in acute coronary syndrome (ACS) and coronary artery disease (CAD). We performed this study to find any possible correlation between serum levels of NT-proBNP and Gensini score in patients diagnosed with ACS.Methods: In a cross-sectional study, 100 consecutive patients with ACS who were candidates of angiography were recruited and their serum levels of NT-proBNP, Gensini scores, lipid profiles and troponin I levels were measured.Results: Sixty six male and 34 female patients with a mean age of 57.5 years, including 44 with unstable angina, 33 with ST-elevation myocardial infarction, and 23 with non-ST-elevation myocardial infarction were enrolled. The mean serum NT-proBNP level and the Gensini score were 1987.16 pg/mL (17.9-8841) and 31.09 (6-92.5), respectively. The serum NT-proBNP levels and Gensini scores were significantly correlated with a Spearman correlation coefficient of 0.953 (P < 0.001). Serum levels of NT-proBNP were not different in patients with single-vessel disease, 2-vessel disease and 3-vessel disease (P = 0.257). NT-Pro-BNP levels were also correlated positively with troponin I levels (correlation coefficient = 0.779) and negatively with left ventricular ejection fraction (correlation coefficient = -0.55). Smoker patients had higher NT-proBNP levels (P = 0.047). Neither Gensini scores nor NT-Pro-BNP levels had significant correlation with lipid profile or blood sugar.Conclusions: NT-proBNP is directly correlated with Gensini score in patients with ACS and might be used as an important marker for risk stratification in those patients.

Introduction: There is little information about the relationship between hyperuricemia and contrast induced nephropathy. The present study aimed to evaluate the relationship between hyperuricemia and contrast induced nephropathy among patients, who had undergone coronary angiography.Methods: In the current study, 200 consecutive patients with coronary artery disease, who underwent coronary angiography in Modarres hospital, were enrolled. According to the available data, the upper limit normal level of uric acid was defined as 7 mg/dl in males and 6.5 mg/dl in females. By increasing level of serum creatinine to 0.5 mg/dl (or 25% enhancement) from basic level of creatinine during 48 hours of introduction of contrast agent, diagnosis of Contrast Induced Nephropathy (CIN) was established. The relationship between hyperuricemia and CIN was then assessed.Results: There is a significant difference between normouricemic patients and hyperuricemic patients, in aspect of weight (P = 0.011) and uric acid (P = 0.001); however, other quantitative and qualitative variables including age, volume of contract agent, creatinine level after angiography, hemoglobin level, gender, arterial access type, number of involved vessels, were insignificant between the two groups (P > 0.05). Moreover, as an essential finding, CIN was shown in 9% of normouricemic patients and 10% of hyperuricemic Â patients with no significant difference between the two groups (P = 0.6).Conclusions: Our study suggests that hyperuricemia may not significantly increase the rate of the contrast-induced nephropathy in patients, who had undergone angiography

Introduction: New techniques for the percutaneous treatment of coronary chronic total occlusions (CTO) have had a high success rate since a few years ago, so the interest for this treatment has been increasing these days.Methods: The current observational study was performed in Modarres hospital as a tertiary referral center. All the patients with documented stable angina who had failed to response to full guideline-mediated medical therapy, referred to our hospital, were candidates for coronary angiography. Antegrade strategy was applied for all these patients. The length of the lesion, the fluoroscopy time of the CTO angioplasty, consumed contrast volume, the number of guide wires used, whether a corsair or tornus micro-catheter was used or not, and the success rate of the angioplasty were documented for further analysis.Results: A total of 47 patients with documented stable angina were finally included. The median age was 59 (45-78) and 70.2% were male. The mean length of the lesion was 34.0 Â± 1.1 .The mean fluoroscopy time and contrast volume were 57.9 Â± 3.2 minutes and 525.9 Â± 20.9 mL, respectively. In average, 2.2 guide wires were used. Corsair and tornus micro-catheters were applied in 30 (63.8%) and 5 (10.6%) of the cases, respectively. Seven complications (all including coronary dissection) occurred. In-hospital major adverse cardiac events (MACE) rate was 10.6%, all of which were non-Q wave myocardial infarction. The success rate was 85.1%. The higher number of used wires, use of corsair, and tornus micro-catheter were not significantly concordant with success rate (P-value > 0.05); in addition, longer lesion was not concordant with unsuccessfulness rate (P-value > 0.05).Conclusions: Patient selection for CTO-angioplasty should be performed more carefully. Patientsâ quality of life and risk of probable procedural complications and future cardiac events should be assessed to decide the best treatment approach. Radiation exposure, contrast consumption and fluoroscopy time are recommended to be monitored during the procedure and thresholds should be defined to enhance safety and efficacy.

Introduction: Use of risk scoring systems in patients with acute coronary syndrome helps with summarizing important prognostic data of the disease and facilitates calculating confidence limits and comparing survival rates between different treatments. In the present study, the researchers first aimed at assessing mid-term outcome of patients with non-ST elevation myocardial infarction (NSTEMI), and then determining main predictors of this outcome to improve definitive criteria for designing a risk scoring system in the population.Methods: In a prospective cohort study, 124 patients with NSTEMI, diagnosed according to ACC/AHA guidelines and hospitalized in an academic hospital in 2013, were consecutively assessed. Baseline characteristics were collected via interviewing, physical examination, and reviewing the recorded files. All the patients were followed for one and six months to assess mid-term outcomes regarding mortality and major adverse cardiac events (MACE). MACE is defined as the occurrence of at least one of the events of death, myocardial infarction, repeated revascularization, or re-hospitalization.Results: One-month death occurred in 3.2%, re-hospitalization in 4.0%, and myocardial infarction in none of the patients. In addition, regarding the six-month outcomes status, mortality rate was determined in 6.4%, re-hospitalization in 22.6%, and myocardial infarction in 4.8% of patients. Hence, one- and six-month MACE rates were 7.3% and 27.4%, respectively. Furthermore, three- and six-month survival rates were estimated to be 96.8% and 93.6%, respectively. According to the Cox-proportion hazard modeling, only reduced left ventricular ejection fraction (LVEF) (HR = 0.909, P = 0.017), history of chronic kidney injury (HR = 8.884, P = 0.005), and Inotrope use (HR = 35.759, P = 0.012) could predict the six-month MACE. None of the other indexes including general coronary risk factors, echocardiography parameters, and level of cardiac enzymes could predict mortality rate.Conclusions: Patients with NSTEMI may face high six-month MACE which can be predicted by low LVEF, history of renal injury and use of inotrope. Therefore, to define risk stratification system, these indicators should be considered as well.
