Aim. To assess the relationship of abdominal obesity with left ventricular systolic function and to predict outcomes in patients with MI within 10 years.Methods. 581 medical records of patients enrolled in the Acute coronary Syndrome Registry between 2008 and 2010 were retrospectively reviewed for the period of 10 years. The following clinical endpoints were collected: all-cause mortality, cardiovascular mortality, recurrent myocardial infarction, stroke, hospitalization due to unstable angina and decompensated heart failure. Baseline left ventricular ejection fraction (LVEF) and the presence of abdominal obesity measured as waist-to-hip ratio were collected in all patients.Results. Abdominal obesity was found in 392 (67.4%) patients admitted with MI. The presence of abdominal obesity did not affect main outcomes within 10 years after the indexed event. Cardiovascular mortality was the lowest among patients with abdominal obesity., an association between abdominal obesity and low cardiovascular mortality was found in patients with intermediate LVEF using the risk stratification data based on the severity of systolic dysfunction at discharge. The highest rate of recurrent hospitalization due to unstable angina was found in patients with abdominal obesity and intermediate LVEF.Conclusion. The prevalence of abdominal obesity in MI patients was high (67%). Abdominal obesity appeared to confer protective effects on the 10-year clinical outcomes in patients with low and intermediate LVEF based on all-cause and cardiovascular mortality. The waist-to-hip ratio were significant in the generation of 10-year allcause and cardiovascular disease mortality prediction models in patients with MI.

Background: Metabolic syndrome confers the risk of developing acute myocardial infarction which is the most common form of coronary heart disease and the single most important cause of premature death worldwide. The frequency and association of different components of metabolic syndrome on AMI are not well understood and has not been well evaluated.Objective: The aim of this study was to assess the components of the metabolic syndrome and its association with AMI patients. This study will help in awareness building in reducing AMI by early detection of components of metabolic syndrome.Patients and methods: This was a prospective observational study consisted of 325 AMI patients who were aged >20 years. Patients with first time AMI arriving in CCU of Rajshahi medical college during the period of 2012-2014, were included. Data were collected through interview, clinical examination, and laboratory tests within 24 hrs of AMI. Five components of metabolic syndrome were defined according to criteria set by modified NCEP ATP III (according to ethnic variation).Results: In AMI patients (n=325), no metabolic components were in 24 (7.4%) patients, one in 53 (16.3%), 2 components in 91(28.0%), 3 components were in 61(18.8%), 4 in 67(20.6%) and all 5 components were in 29 (8.9%) patients. In this study, there was no component in 7.4% of AMI patients, at least 1 component was 92.6%, at least 2 components were 76.3%, at least 3 components were 48.3%, at least 4 components were 29.5% and at least 5 components were 8.9%. The Metabolic syndrome was 48.3% (n=157). Among metabolic syndrome (≥3 components) in AMI (n=157, 48.3%) 4 components (20.6%) were more, next was 3 components (18.8%) and than 5 components (8.9%). Overall frequencies of components in acute myocardial infarction (n=325) were in order of abdominal obesity (54.8%) > high blood pressure (54.5%) > high FPG (54.2%) > Triglyceride (46.2%) and low HDL-C (46.2%) in acute myocardial infarction. Highest percentage was observed in abdominal obesity (54.8%) followed by high blood pressure (54.5%) and FPG (54.2%).TAJ 2016; 29(2): 6-10

Isolated ST-segment elevation only in the aVR lead, reflecting an acute myocardial infarction due to a left main coronary artery occlusion, was ignored as part of physicians' training in emergency medicine for a long time. The recognition of aVR lead elevation is becoming more accepted as a mandatory diagnostic tool, in particular for physicians working at emergency departments. We report a typical myocardial infarction with total occlusion of the proximal part of the left anterior coronary artery, presenting with ST-segment elevation in the aVR lead, which was misinterpreted as diffuse ischemia. The lacking mandatory awareness of this entity endangered prompt and correct treatment.

The Relationship

Objectives. The primary objective of this study was to determine the relationship between waist-to-hip ratio (WHR), cardiovascular (CV) events, and mortality in peritoneal dialysis (PD) patients. A secondary objective was to investigate the association between abdominal obesity and systemic inflammatory markers.Methods. This is a prospective study of 22 prevalent PD patients. WHR was measured at baseline. C-reactive protein (CRP), tumour necrosis factor-α(TNF-α), and interleukin-6 (IL-6) were measured. Main outcomes were first CV event and death from all causes. Survival analysis was used to examine the relationship between anthropomorphic measures and clinical outcomes.Results. Mean follow-up period was 3.1 years. In Kaplan-Meier analysis, survival was lower in those with higher WHR (P=.002). In Cox regression, WHR independently predicted mortality and first CV event after adjustment for known ischemic heart disease (hazard ratio [HR] 1.17, confidence interval [CI] 1.05–1.30 for death; HR 1.13, CI 1.01–1.26 for CV event). WHR correlated with serum TNF-α(r=0.45;P=.05).Conclusion. The results of this study suggest WHR may be a risk factor for increased CV events and mortality in PD patients. Abdominal obesity is also associated with inflammatory markers. Larger studies are warranted to confirm these findings.

Aim. To assess the association of smoking status and smoking intensity with general and abdominal obesity in a sample of middle-a ged men.Material and methods. This study was conducted as a part of the 32-year prospective cohort observation of males from childhood (11-12 years of age). The study included 301 (30,0%) representatives of the initial population sample aged 41-44 years. Age, anthropometric parameters, relationship of smoking status and smoking intensity with general (overweight/obesity) and abdominal obesity were analyzed.Results. Overweight/obesity were more common in former smokers (78,1%) compared with non-smokers (58,7%; p<0,01). Abdominal obesity, estimated by the waist circumference (WC), was detected more often among former (57,5%) and current smokers (50,7%), and abdominal obesity, estimated by the waist-to-hip ratio, was more common among current smokers, compared with non-smokers (37,0%; p<0,01, p<0,05 and p<0,05 respectively). A direct linear relationship was found between the intensity of current smoking and indicators of abdominal obesity in terms of waist-to-hip ratio (P for trend=0,004) and a direct linear relationship between intensity of former smoking and general obesity estimated by BMI (P for trend = 0,001), and abdominal obesity estimated by waist-tohip ratio (P for trend=0,004). The probability of developing abdominal obesity in current smokers with WC≥94,0 cm and with waist-to-hip ratio ≥0,9 was 1,8 and 2 times higher, respectively, than in non-smokers, but lower compared to former smokers. The risk of overweight/obesity and abdominal obesity in former smokers was 2,5 and 2,3 times higher, respectively, than in non-smokers. The 10-year risk of fatal CVD in nonsmokers and former smokers was lower than in current smokers (0,8% and 0,9% vs 1,8%; p<0,001 and p<0,001, respectively).Conclusion. High intensity of smoking among current smokers is associated with a higher probability of developing abdominal obesity, and in former smokers — with a higher probability of developing general and abdominal obesity. Former smokers, compared to current smokers, are at a lower risk of developing fatal cardiovascular diseases. Smoking cessation activities should be aimed at minimizing weight gain after quitting smoking and developing tobacco control programs.

We carried out case control study aimed to evaluate abdominal obesity as a risk factor for ischemic stroke. Though it became established as a risk factor for cardiovascular disease, still its association with stroke is less clear. We have taken ninety cases with ischemic stroke and compare waist to hip ratio & waist circumference with same numbers of age and sex matched stroke free people as controls. There are standard markers of abdominal obesity & their cut-off values and ways of measurement were taken from International Diabetic Federation. Both increase waist to hip ratio (63.3% in cases & 26.7% in controls) and increase waist circumference (66.7% in cases & 25.6% in controls) were significant (P<.05) and showed marked strength of association (odds ratio >1) in ischemic stroke patients. After adjusting the significant risk factors in all age and sex matched cases and controls by conditional logistic regression analysis, WHR and WC still showed significant strength of association with ischemic stroke in all groups. The increase abdominal obesity markers were found to have greater association in both female and male cases in relation to their control counterparts. So, in the light of current study we may suggest that abdominal obesity defined as increase waist circumference and waist to hip ratio attribute considerably to the estimate of ischemic stroke events.
