ABSTRACT
Background: The elevation of troponin-T (Trop-t) and creatinine kinase myocardial isoform (Ckmb) and elevation of these markers lead to major adverse cardiac events (MACEs). The association between above-mentioned parameters along with electrocardiogram (ECG) changes can be suitable diagnostic tool for myocardial injury following percutaneous coronary intervention (PCI). The present study was attempted to know the association of the changes in surface ECG and cardiac biomarkers and MACEs following PCI with the outcome in follow up among patients in eastern India. Methods: In present study, 100 patients were randomly selected for coronary angioplasty between April2012 to March2013. All the cases were referred to catheterization laboratory for elective PCI for single vessel or multivessel in native coronary artery. The biomarkers such as trop-t and Ckmb and MACEs along with changes in ECG were estimated as per standard protocol. Results: ECG changes were statistically significantly correlated with post procedure Trop-t elevation (p<0.001), Ckmb elevation (p<0.001) and MACEs (P<0.01 and p<0.001) in 6 months followed up. Conclusion: In conclusion, the present study showed significant relationship between MACEs during followed up and changed in surface ECG along with Trop-t and Ckmb elevation in the post-PCI period of six-month followed up in stable ischaemic heart disease.
ABSTRACT
Background: Hypertension is the most common illness of circulatory system and is a worldwide health challenge affecting both developed and developing nations. The development of hypertension is a multi-factorial process and the risk factors for its development are many such as genetic factors, obesity, age & sex factors, salt sensitivity, dyslipidemia, hyperinsulinemia & insulin resistance, environmental factors, socio economic imbalances, free radicals/reactive Oxygen species, oxidative stress, blood groups etc. The role of blood groups in the etiology of essential hypertension has long been suspected. Methods: The study design was a cohort study consisting of 15 hypertensive patients of the A, B, AB and O each. Anthropometric parameters such as Blood pressure (SBP/DBP) and Body Mass Index (BMI) and Biochemical parameters such as Blood grouping, Blood Glucose levels, Haemoglobin levels, Lipid profile, which included Triglycerides, Total cholesterol, HDL cholesterol and LDL and VLDL cholesterol, were measured using standardized methods. The various parameters were compared between hypertensives of the various blood groups and statistical analysis was done using SPSS. Mean and SD of each group was calculated, and Unpaired student’s t-test was applied (P < 0.05 considered as significant). Results: When BMI was compared among hypertensive groups we observed significant increased level of BMI in group A as compared to group O hypertensives. (10.36%; P<0.05). While comparing SBP between hypertensive groups we observed significant raised level of SBP in group A as compared to group B (9.38%; P<0.01) and O (10.45%; P<0.01). Similarly, DBP was found to be increased significantly in group A as compared to group B ((5.34%; P<0.05) and O hypertensive patients (5.06%; P<0.001). LDL-C and HDL-C were non-significantly altered in these groups however value of VLDL-C was found increased in group A as compared to group O hypertensives (20.38%; P< 0.05). Conclusion: The study concluded that there is a significantly higher SBP and DBP in the hypertensives of the A blood group as compared to the hypertensives of the B and O blood groups. It also found increased levels of serum triglycerides, total cholesterol, LDL-C, VLDL-C along with decreased levels of HDL-C was in hypertensive patients predominantly in group A and AB hypertensive. The hypertensive patients of A blood group have shown a statistically significant increase in BMI as compared to hypertensives of the other blood groups.
ABSTRACT
Background: Cardiac troponin (CTnT) and creatinine kinase myocardial isoform (CKMB) are suitable marker for myocardial injury following percutaneous coronary intervention (PCI). Elevation of these markers lead to major adverse cardiac events (MACEs). The objective was to detect the elevation of serum CTnT and CKMB during post-PCI period and identify MACE during six-month followed up among patients in eastern Indian. Methods: In present study, 100 patients were randomly selected for coronary angioplasty between April2012 to March2013. All the cases were referred to catheterization laboratory for elective PCI for single vessel or multivessel in native coronary artery. The CTnT and CKMB parameters were estimated as per standard protocol. The categorization was done on the basis of baseline (normal value), ≤3time and >3time elevation for both the biomarkers and respective MACEs as MACE-1, MACE-2, MACE-3, MACE-4 and MACE-5 were determined. Results: There were more MACE in patients in six month follow up who sustainned >3times elevation in CTnT and CKMB during pos-PCI period. There was highly significant correlation (P<0.001 and P<0.01) with increasing trend of CTnT and CKMB elevation and risk of MACEs. MACEs were significantly (P<0.001 and P<0.01) correlated with diabetes mellitus, hypertension, renal dysfunction, fluoroscopy time, stent length, left ventricular ejection fraction and type of lesion. It was also observed that more hospital stay led to elevation of CTnT and CKMB. Conclusions: It is concluded that the elevation of CTnT and CKMB in serum during post-PCI can predict MACEs in six-month follow up in stable ischaemic heart disease.
