Background:Cigarette smoking induced increased sympathetic activity is one of the major independent risk factor for cardiac morbidity and mortality. Objective:To assess acute effects of smoking on neuro cardiovascular regulation by analysis of time domain measures of HRV in current regular healthy male cigarette smoker. Methods:This comparative analytical study was conducted in the Department of Physiology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Shahbag, Dhaka from July 2011 to June 2012. 120 apparently healthy male current regular cigarette smoker aged 20-55 years were participated in the study group. Age and BMI matched 70 apparently healthy male non smoker subjects were studied as control. To observe the acute effects data were recorded 5 and 30 min after finishing a cigarette. Time domain measures of HRV were recorded by a RMS digital polyrite D. Statistical analysis was done by independent sample t test and paired sample t test. Results: Resting pulse rate, SBP, DBP, mean heart rate were significantly higher (p<0.001) and mean R-R interval, SDNN, RMSSD and total power were significantly lower (p<0.001) in all smokers in comparison to those of healthy control.In addition, all time domain parameters were significantly decreased from their corresponding baseline value just 5 minutes after smoking and returned close to their baseline value after 30 minutes of smoking but it remained significantly lower than control value. Conclusion: The result of this study concludes that cigarette smoking had acute effect on cardiac autonomic function causing depressed vagal activity and overbalance of sympathetic function.

The use of Cannabis sativa is on the increase worldwide especially among adolescents and youths. This study investigated the effect of cannabis smoking on renal functions in young and apparently healthy male students of Nnamdi Azikiwe University, Nnewi campus, Anambra state, Nigeria. A total of 60 male (40 cannabis smokers and 20 controls) subjects participated in this study. A well-structured questionnaire was used to obtain the demographic data and anthropometric of subjects. Thereafter, 5mls of fasting blood sample was collected from the subjects into plain container for the estimation of biochemical parameters (creatinine, urea, uric acid, electrolytes). Renal parameters were estimated using standard methods. Data obtained were statistically analyzed using paired student t-test and pearson r correlation. Result showed that the mean serum levels of urea, creatinine, K+, Na+, Cl-, ionized calcium, total calcium, total carbon dioxide, anion gap, and pH were not significantly different in both smokers and control subjects(p>0.05). However, there was significantly higher mean serum level of uric acid (2.42 ± 38.54 vs 1.92 ± 41.61; p<0.05) and total calcium (16.0 ± 0.30 vs 10.24 ± 0.18; p<0.05) in smokers compared with control subjects. Again, BMI was significantly higher in smokers compared with non-smokers (23.96 ± 3.15; p<0.05 Vs 21.95 ± 2.17; p<0.05). Therefore, cannabis use had no deleterious effect on the kidneys, but the significantly higher uric acid levels in the smokers may provide some anti-oxidant protection. However, further studies are necessary to further unravel the full potentials of cannabis use.

Abstract Background Both unstable angina (UA) and non-ST-segment elevation myocardial infarction (NSTEMI) are still classified together in non-ST-elevation acute coronary syndromes despite the fact they substantially differ in both clinical profile and prognosis. Purpose The aim of the present study was to evaluate contemporary clinical characteristics and outcomes of UA patients after percutaneous coronary intervention (PCI) in comparison with stable angina (SCAD) and myocardial infarction (NSTEMI as well as STEMI) in Swietokrzyskie District of Poland in years 2014–2017. Methods A total of 7'187 patients after PCI from ORPKI Registry (38% with diagnosis of UA) were included into the analysis. Impact of clinical presentation (UA, SCAD, NSTEMI, STEMI) on 3-year outcomes were determined. Results UA patients were older that SCAD but younger than NSTEMI individuals. Diabetes and hypertension were more often encountered into UA group than in NSTEMI but less often than in SCAD cases. In UA group the percentage of previous myocardial infarction (MI), PCI or coronary artery bypass grafting (CABG) was the highest among all analyzed groups. In 3-year observation the risk of death as well as myocardial infarction (MI) and major adverse cardiac events (MACE) in unstable angina after PCI was higher than in stable angina but considerably lower than in NSTEMI group. Multivariate analysis confirmed that prognosis in NSTEMI was substantially worse in comparison with UA (RR 1.365, 95% CI: 1.126–1.655, p=0.0015). On the contrary there were no difference in mortality risk between UA and SCAD patients (RR 1.189, 95% CI: 0.932–1.518, p=0.1620). Parallel results were observed in respect of MI and MACE. Independ predictors of death were: age, kidney disease, hypertension, diabetes, previous stroke or previous PCI. Multivariate logistic regression analyse Clinical presentation Death Myocardial infarction MACE RR 95% CI p-value RR 95% CI p-value RR 95% CI p-value NSTEMI/UA 1.365 1.126–1.655 0.0015 1.822 1.076–3.055 0.0260 1.514 1.267–1.807 <0.0001 NSTEMI/SCAD 1.624 1.251–2.109 0.0003 1.882 0.982–3.789 0.0568 1.604 1.275–2.094 <0.0001 UA/SCAD 1.189 0.932–1.518 0.1620 1.033 0.557–2.034 0.9219 1.060 0.855–1.323 0.6023 MACE, major adverse cardiac events; NSTEMI, non-ST-segment elevation myocardial infarction; UA, unstable angina; SCAD, stable angina. Conclusion Unstable angina accounted for 38% of all cases and was the most common diagnosis in patients that underwent PCI in that time. 3-year prognosis in UA was considerable better in comparison with NSTEMI. On contrary there was no difference in outcomes (death, MI, MACE) between UA and SCAD patients.

BackgroundMost cell therapy trials failed to show an improvement in global left ventricular (LV) function measures after myocardial infarction (MI). Myocardial segments are heterogeneously impacted by MI. Global LV function indices are not able to detect the small treatment effects on segmental myocardial function which may have prognostic implications for cardiac events. We aimed to test the efficacy of allogeneic cardiosphere-derived cells (CDCs) for improving regional myocardial function and contractility.MethodsIn this exploratory analysis of a randomised clinical trial, 142 patients with post-MI with LVEF <45% and 15% or greater LV scar size were randomised in 2:1 ratio to receive intracoronary infusion of allogenic CDCs or placebo, respectively. Change in segmental myocardial circumferential strain (Ecc) by MRI from baseline to 6 months was compared between CDCs and placebo groups.ResultsIn total, 124 patients completed the 6-month follow-up (mean (SD) age 54.3 (10.8) and 108 (87.1%) men). Segmental Ecc improvement was significantly greater in patients receiving CDC (−0.5% (4.0)) compared with placebo (0.2% (3.7), p=0.05). The greatest benefit for improvement in segmental Ecc was observed in segments containing scar tissue (change in segmental Ecc of −0.7% (3.5) in patients receiving CDC vs 0.04% (3.7) in the placebo group, p=0.04).ConclusionsIn patients with post-MI LV dysfunction, CDC administration resulted in improved segmental myocardial function. Our findings highlight the importance of segmental myocardial function indices as an endpoint in future clinical trials of patients with post-MI.Trial registration numberNCT01458405.

Abstract Background The SYNTAX II score (SS-II) can predict 4-year outcomes in patients with complex coronary artery disease and ST-segment elevation myocardial infarction (STEMI). Nonetheless, the prognostic value of SS-II for a cardiogenic shock (CS) in the setting of STEMI has not been assessed. Purpose This study aimed to investigate the predictive impact of SS-II in patients with CS complicating STEMI undergoing primary percutaneous coronary intervention, and whether SS-II adds prognostic information to predict major adverse cardiac events (MACE) and all-cause death in this population. Methods This prospective cohort study included 1965 consecutive patients with STEMI who underwent primary-PCI between January 2008 and December 2017. The cohort of patients with CS (n=153) was identified and divided into three groups based on SS-II tertiles [SS-II low tertile &lt;38 (n=51), ≥38 SS-II intermediate tertile &lt;47 (n=51), and SS-II high tertile ≥48 (n=51)]. Results Amongst the cohort of patients with CS mean age was 68.4±14.0 years, 69.2% were male and 51.6% presented with anterior STEMI (mean SSII was 45.1±14). In-hospital mortality was significantly higher in the high SS-II tertile (85.7% vs. 38.9% vs 24.4%, p≤0.001) compared with SS-II intermediate and low tertiles. During follow-up (median 2.5 years), SS-II was positively correlated with MACE (89.3% (high SS-II) vs. 52.8% (int SS-II) vs. 42.2% (low SS-II), p≤0.001), and with all-cause mortality (89.3% vs 44.4% vs 26.7%, p≤0.001). The SS-II was also an independent predictor of MACE (HR=1.042, 95% CI: 1.020–1.063, p=0.000) and all-cause mortality during follow-up (HR=1.056, 95% CI: 1.033–1.079, p=0.000) Conclusion In a real-world cohort of patients with STEMI related CS, the SS-II added important prognostic information, being an independent predictor of MACE and all-cause mortality during follow-up.

Abstract Background/objectives Pericoronary adipose tissue inflammation might lead to the development and destabilization of coronary plaques in prediabetic patients. Here, we evaluated inflammation and leptin to adiponectin ratio in pericoronary fat from patients subjected to coronary artery bypass grafting (CABG) for acute myocardial infarction (AMI). Furthermore, we compared the 12-month prognosis of prediabetic patients compared to normoglycemic patients (NG). Finally, the effect of metformin therapy on pericoronary fat inflammation and 12-months prognosis in AMI-prediabetic patients was also evaluated. Methods An observational prospective study was conducted on patients with first AMI referred for CABG. Participants were divided in prediabetic and NG-patients. Prediabetic patients were divided in two groups; never-metformin-users and current-metformin-users receiving metformin therapy for almost 6 months before CABG. During the by-pass procedure on epicardial coronary portion, the pericoronary fat was removed from the surrounding stenosis area. The primary endpoints were the assessments of Major-Adverse-Cardiac-Events (MACE) at 12-month follow-up. Moreover, inflammatory tone was evaluated by measuring pericoronary fat levels of tumor necrosis factor-α (TNF-α), sirtuin 6 (SIRT6), and leptin to adiponectin ratio. Finally, inflammatory tone was correlated to the MACE during the 12-months follow-up. Results The MACE was 9.1% in all prediabetic patients and 3% in NG-patients. In prediabetic patients, current-metformin-users presented a significantly lower rate of MACE compared to prediabetic patients never-metformin-users. In addition, prediabetic patients showed higher inflammatory tone and leptin to adiponectin ratio in pericoronary fat compared to NG-patients (P < 0.001). Prediabetic never-metformin-users showed higher inflammatory tone and leptin to adiponectin ratio in pericoronary fat compared to current-metformin-users (P < 0.001). Remarkably, inflammatory tone and leptin to adiponectin ratio was significantly related to the MACE during the 12-months follow-up. Conclusion Prediabetes increase inflammatory burden in pericoronary adipose tissue. Metformin by reducing inflammatory tone and leptin to adiponectin ratio in pericoronary fat may improve prognosis in prediabetic patients with AMI.
