Item Congenital solitary nonparasitic cyst of the liver in an infant.(1985-04-01) Chatterjee, H; Bhat, S M; Reddy, K S; Barua, S K; Sankaran, VItem Correlation of Heart Rate Variability and 24- hour Mean Heart Rate with TIMI Risk Score in Acute ST-Segment Elevation Myocardial Infarction.(2011) Chakrovortty, S K; Khan, M R; Kundu, S; Barua, S K; Dutta, B; Uddin, M N; Islam, A K M M; Majumder, A A SBackground: Thrombolysis In Myocardial Infarction (TIMI) risk score, heart rate variability (HRV) and 24hour mean heart rate all are important predictor of prognosis after ST segment elevation myocardial infarction(STEMI). Correlation among these factors has not been studied thoroughly. Methods: This study was conducted in NICVD (National Institute of Cardiovascular Diseases), Dhaka, from July 2008 to June 2009. Total 105 STEMI patients were included in the study. TIMI risk score were calculated and each patient under went 24hour Holter monitoring. SDNN for HRV and mean RR interval for mean heart rate were recorded. Results : Ninety one patients (mean age 53.9 ± 10.8 years), 86.7% were males and 14( mean age 59.8 ± 8.8 years), 13.3% were female. Stratification of subjects by TIMI risk score shows that nearly 60% had risk score in the range of 3 – 7, 17. % between 0 – 2 and 24% 8 or more than 8.SDNN and RR interval stratified by TIMI risk score demonstrates that both the variables decreases significantly with the increase of TIMI risk score. Among the TIMI risk groups SDNN values were 120.0 ± 19, 871.0 ± 20.5 and 40.9 ± 6.4 msec in mild, moderate and high risk group respectively(p=<0.001). Mean RR were 836.8 ± 121.0, 776.7 ± 130.3 and 649.7 ± 75.5 msec in low, intermediate and high risk group respectively(p<0.001). There was a significant correlation between depressed SDNN and high TIMI risk score (r=.893, p=.001). High TIMI risk score also showed a negative correlation with mean RR interval (r=-574, p<0.001). Mean RR and SDNN show a perfect linear relationship (r = 0.657, p < 0.001). Conclusion: It was observed that depressed heart rate variability and increased 24-hours mean heart rate correlates with high TIMI risk score after acute ST-elevation myocardial infarction.Item Impact of Low Hemoglobin on Contrast-Induced Nephropathy After Percutaneous Coronary Intervention.(2012) Akhtaruzzaman, M; Choudhury, A K; Khalequzzaman, M; Barua, S K; Choudhury, T A; Hasem, S; Majumder, N K; Islam, A K M Monwarul; Chowdhury, S; Chowdhury, A H KBackground: Contrast-Induced Nephropathy (CIN) is an iatrogenic disorder, resulting from exposure to contrast media. The aim of this study was to assess whether anaemia is a predictor of contrast induced nephropathy after Percutaneous Coronary Intervention (PCI). Methods: This was a prospective observational study. A total of one hundred patients fulfilling the inclusion and exclusion criteria who underwent (PCI) Percutaneous Transluminal Coronary Angioplasty with stenting, were studied during the study period of two years from January 2008 to December 2009. Patients were divided into two groups : Group-I (n=50), patients with low hemoglobin (male <13-10gm/dl, female < 12-10 gm/dl) and Group-II (n=50), patients with normal hemoglobin (male >13gm/dl, female >12gm/dl). Non-ionic low-osmolar contrast agents was used in all patients.Volume of contrast medium (ml) was recorded. Adequate hydration given intravenously (ml). Prior to procedure serum creatinine, serum electrolytes and Creatinine clearance rate were measured within 24 hrs before PCI and on days 1,2,3 after PCI. If there is renal impairment (CIN) serum creatinine, serum electrolytes and Creatinine clearance rate were measured daily from the 4th day onward after PCI until recovery. Results: The mean serum creatinine level of low hemoglobin group and normal hemoglobin group were 0.9mg/dl and 1mg/dl respectively at base line. The low hemoglobin group experienced a considerable increase in serum creatinine up to 1.5mg/dl at day 3 compared to 1.3 mg/dl in normal hemoglobin group. When the most common definition of contrast induced nephropathy (as an increase in the serum creatinine concentration >0.5 mg/dl from baseline) was used the incidence of CIN was 26% in low hemoglobin group and 8% in the normal hemoglobin group. Conclusion: preprocedural low hemoglobin is an independent determinant of increased incidence of contrast induced nephropathy after percutaneous coronary intervention.
