ABSTRACT
Background: Spontaneous echocardiographic contrast (SEC) is a risk factor for left atrial thrombus formation and an important indicator of potential systemic embolism originated from heart. An established relation exists between the inflammatory status and the prothrombotic state. The present study was conducted to evaluate the association between left atrial spontaneous echocardiographic contrast with inflammatory markers in mitral stenosis patients. Methods: This observational analytical study was undertaken in the department of Cardiology, National Institute of Cardiovascular diseases (NICVD), Dhaka. A total of 70 patients with mitral stenosis were categorized into two groups: group I with left atrial SEC and group II without left atrial SEC. All patients underwent transthoracic as well as transoesophageal echocardiography. Complete blood count with ESR was done and neutrophil lymphocyte ratio was calculated. The high sensitive C-reactive protein (hs-CRP) was assayed. Results: The hs-CRP levels were significantly greater in the SEC-positive group (5.6±2.1vs 1.5±0.7, p=0.001). The mean ESR level was significantly greater in the SEC-positive group (32.6±15.5 mmvs15.8±4.7 mm).The neutrophil levels ((76.1±1.9 vs 63.7±3.3) were significantly greater in the SEC-positive group, and the lymphocyte levels (33.3±3.0 vs 21.5±1.3) were significantly greater in the SEC-negative group (p=0.001 for each). The neutrophil/lymphocyte (N/L) ratio was also significantly greater in the SEC-positive group (3.4±0.4 vs2.1±0.6, p=0.001).On multivariate analysis hs-CRP, neutrophil/lymphocyte ratio, raised ESR, mitral valve area and left atrial diameter were independent risk factors for SEC in patients with mitral stenosis. Conclusion: From this study it may be concluded that left atrial SEC is associated with raised inflammatory markers in majority of patients with mitral stenosis. So, SEC may be considered as a reflection of ongoing inflammatory process in patients with mitral stenosis.
ABSTRACT
Background: Cardiovascular disease is the leading cause of morbidity and mortality in renal impaired patients. Many of the patients of chronic kidney disease die of cardiovascular disease before requiring dialysis. Cardiovascular disease in renal impaired patient is potentially preventable and treatable. The aim of this study was to evaluate the association between renal impairment and coronary artery disease severity in chronic stable angina patients. Methods: 110 patients with chronic stable angina who got admitted for coronary angiography were included in the study. They were divided into impaired renal function group (with estimated glomerular filtration rate [eGFR] <90 ml/min/1.73m2) and normal renal function group (eGFR e” 90 ml/min/1.73m2) on the basis of eGFR. The severity of the CAD was assessed by angiographic Vessel score and Gensini score. Results: Mean Gensini score was significantly high in impaired renal function group (42.30±24.9 vs 25.65±17.9, p <0.05). There was significant negative correlation between eGFR and vessel score (r=-0.30, p <0.05) and between eGFR and Gensini score (r =-0.65, P <0.05). In multivariate logistic regression analysis, after adjustment of factors eGFR remain independent predictors of severe CAD (P=0.002, OR -5.73). Conclusion: Impaired renal function, assessed by eGFR is associated with angiographic severe coronary artery disease in chronic stable angina patients and this association is independent of conventional cardiovascular risk factors.
