Abstract

Background. Atrial fibrillation (AF) is a common arrhythmia after acute myocardial infarction (AMI).Mortality in AMI patients with AF also been shown to be up to twice as high as for those without AF. Nonhemorrhagic stroke occurs in 0.1% to 1.3%of patients with acute myocardial infarction who are treatedwith thrombolytic, with substantial associated mortality andmorbidity.The aim of this study is toelaborate correlation between in hospital AF with long term stroke event inST-elevation myocardial infarction(STEMI) patients who treated with thrombolytic .Methods. Two hundred and thirty STEMI patients (27-72 yo) treated with thrombolytic agent were studied retrospectively. The study end point was Major Cardio-Cerebrovascular Event (MACCE) during 3 years follow up.Results. Eleven patients experience AF episode during STEMI hospitalization. During 3 years follow up 24 patients (10.4%) experienced MACCE which comprised of : cardiac death 4 (1.7%), fatal infarction 2 (0.9%), non fatal infarction 13 (5.7%) and stroke 5 (2.2%). Independent clinical variables were not significant as a predictor for the occurrence of future stroke event, except atrial fibrillation episode (HR 13.4; p<0.005)that was encountered during hospitalization in the setting of AMI.Conclusion. In-hospital AF in STEMI patients treated with thrombolytic agent is a predictor of long term stroke.

Abstract

Hipertensi merupakan penyebab utama tingginyamorbiditas dan mortalitas kardiovaskular. Estimasiprevalensi hipertensi di seluruh dunia hampir 1 milyarorang, dan sekitar 7,1 juta kematian pertahundisebabkan oleh hipertensi. Hipertensi jugamerupakan masalah kesehatan yang utama dan seringdijumpai di Indonesia. Prevalensi hipertensi di Indonesiamasih tinggi. Studi berkesinambungan dari MonitoringTrends and Determinants of Cardiovascular Disease(MONICA) Jakarta melaporkan adanya peningkatanprevalensi hipertensi pada populasi Indonesia dari 16,9%(tahun 1993) menjadi 17,9% (tahun 2000)

Abstract

Background. Obesity is one of Cardiovascular risk factor. Obesity caused increase in heart mass due to cellular hypertrophic and metaplastic proses, independently of hemodynamic factors such as blood pressure. There were hyperleptinemia in obesity due to the selective Leptin resistency in central nervous system and peripheral organs. Study with cultured rat cardiomyocyte have shown hypertrophy and hyperplastic effect of Leptin to cardiomyocyte. Some clinical studies have shown correlation between circulating Leptin level with Left Ventricle Mass in hypertensive and insulin resistance men.Objective. This study aimed to elaborate the correlation between circulating Leptin level with Left Ventricle Mass in normotensive men.Methods. A cross sectional study was performed with normotensive men, which included 40 obese normotensive and 40 normoweight men. All patients underwent physical and laboratory assessment and examination of Left Ventricle with echocardiography. The circulating Leptin level were determined by ELISA method. The Leptin level were expressed as median (25th percentile; 75th percentile)Results. The circulating Leptin level were significantly different between the obese normotensive and the lean group. The Left Ventricle Mass in Obese increased, although have not fulfilled the criteria for Left Ventricle Hypertrophy. There were significant correlation between Left Ventricle Mass with BMI (r = 0,711; p<0,001) and waist circumference (r = 0,732; p<0,001). Respectively, there were significant correlation between Left Ventricle Mass Index with BMI (r = 0.541; p<0.001) and waist circumference (r = 0,558; p<0.001. There were significant correlation between circulating Leptin level with Left Ventricle Mass (r = 0,510; <0,001) and Left Ventricle Mass Index (r = 0,414; p<0,001) inobese  men.Conclusion. Circulating Leptin level is correlated with Left Ventricle Mass in normotensive men.

Abstract

Background. Obesity is associated with increase arterial stiffness and elevated plasma endothelin-1 concentration. However, there is still conflicting data regarding the effect of obesity on arterial stiffness and plasma endothelin-1 concentration.Objective. The purpose of the current study was to assess this effect and analyze whether there was correlation between arterial stiffness indices and plasma endothelin-1 concentration.Methods. The design of the study was cross sectional study that compare and correlate arterial stiffness and plasma endothelin-1 concentration between obesity group (n=40) and normoweight group (n=40). Obesity was defined as body mass index = 25 kg/m2. Arterial stiffness was assessed by measuring carotid-femoral pulse wave velocity (PWV) dan β stiffness index (β) non-invasively using ultrasound method. Endothelin-1 was measured by ELISA.Results. There was no significant difference regarding PWV between obesity and normoweight group (mean ± SD: 809.44 ± 137.77 versus 850.96 ± 211.60 cm/s, p=NS), but β was significantly higher in obese group (8.79 ± 3.15 versus 7.28 ± 1.96, p=0.012). PWV and β correlated significantly with age (PWV: r=0.446, p<0.001, β : r=0.354, p=0.001), but only β correlated with body mass index (r=0.282, p=0.011) and waist circumference (r=0.312, p=0.005). There was no significant difference between obesity and normoweight group regarding plasma endothelin-1 concentration (0.94 ± 0.26 versus 0.95 ± 0.18pg/dl, p=NS). There are no significant  correlations  between PWV/β andplasma endothelin-1 concentration.Conclusions. These findings suggest that the effect of obesity on arterialstiffness is not uniformly seen  throughout all arterial region. Obesity impact on carotid artery is greater than its impact on aorta, and this impact on arterial stiffness is not mediated by endothelin-1.
