ABSTRACT
Background: Myocardial Infarction (MI) is the term given for a state of myocardial necrosis which is secondary to an acute interruption of the coronary blood supply. Severity is dependent on level of occlusion, length of time of occlusion and presence or absence of collateral circulation. Myocardial infarction is now considered part of a spectrum referred to as acute coronary syndrome. It is a spectrum of acute myocardial ischemia that also includes unstable angina (STEMI) and non-ST segment elevation myocardial infarction (NSTEMI). The changes in serum electrolytes were studied in this study with a special focus on sodium and potassium serum levels in patients suffering from AMI. Hence, the aim of the study was to examine the changes in serum electrolytes among AMI patients and then comparison was done with the healthy persons.Methods: The study comprised of 80 subjects, which were divided equally into study group and control group. The study group comprised cases of confirmed diagnosis of recent onset of AMI. Clinical data was collected using interviewing questionnaires. The blood samples of both groups were analysed for serum electrolytes (Na+, K+, Cl-, Ca+ and Mg+) with the help of ion sensitive electrode analyser along with quality control sera.Results: There was statistically significant decrease in sodium and potassium levels in AMI patients. It was found that there was decrease in sodium serum levels in AMI patients suffering with hypertension. Potassium levels were increased in AMI patients suffering from Diabetes Mellitus and Hypertension, which was found to be statistically significant.Conclusions: Hyponatremia and hypokalemia are indicators of acute myocardial infarction. Serum sodium and potassium levels are prognostic indicators, i.e., rise in sodium levels after initial fall was indicative of clinical improvement. Therefore, estimation of sodium and potassium level in acute MI patients can help assess their prognosis.
ABSTRACT
Background: Aim of the study was to evaluate the primary procedural success of Multivessel Percutaneous coronary intervention in patients with acute ST-segment elevated myocardial infarction at the same sitting. Methods: Total 23 (13.4%) patients were enrolled in this very preliminary study, among the total 171 patients who had primary PCI at our center from Jan 2010 to February 2015. Among them, Male: 20 and Female: 3. Total 52 stents were deployed in 46 territories. Mean age were for both male and female were 54 yrs. Associated coronary artery disease risk factors were Dyslipidemia, High Blood pressure, Diabetes Mellitus, positive family history for coronary artery disease and Smoking. Results: Among the study group; 17(74%) were Dyslipidemic, 11(47.8%) were hypertensive; 8(34.8%) patients were Diabetic, positive family history 4(17.4%) and 9(39%) were all male smoker. Female patients were more obese (BMI: M 26: F 27). Common diagnosis at admission based on ECG evidence was; Inferior wall myocardial infarction: 12 (52.2%), Anterior wall myocardial infarction 9(39.1%) and lateral 2(8.7%). Common stented territory was left anterior descending artery 9(39.1%), right coronary artery 7(30.4%), and left circumflex artery 7(30.4%). Stent used: Bare metal stent 3 (5.7%), DES: 49 (94.2%). Among the different drug eluting stents, Everolimus 26 (52%), Sirolimus 8(15.4%) and Zotarolimus 9(17.3%), Paclitaxel 2 (3.8%), Biolimus 2 (3.8%), Genous 2 (3.8%). Conclusion: In the current prospective non randomized study, we found that the multivessel primary PCI for ST elevation myocardial infarction with non-culprit vessel are suitable for PCI at the same sitting with better in-hospital and 1 yr survival outcome.
ABSTRACT
BACKGROUND: Doppler echocardiography is a non-invasive technique that has been used to evaluate LV diastolic dysfunction. Impaired left ventricular diastolic filling is known to occur in patients with coronary artery disease. Compared with those in normal subjects, Doppler-derived transmitral blood flow velocities have been reported to be reduced during early diastolic filling and to be compensatory elevated subsequent to atrial systole in patinets with coronary artery disease. But stiffness of myocardium normalize the E/A ratio, and normal E/A ratio may reveal increased ventricular filling pressure. We tried to investigate left ventricular filling parameters by Doppler echocardiography in patients with early myocardial infarction, and to compare left ventricular diastolic function regarding infarct location on EKG, one or multivessel disease on coronary angiography, and treatment modality. METHODS: From September 1993 to August 1995, Pulsed wave Doppler echocardiography was performed in patients with early acute myocardial infarction(N=95) and control group(N=20) within 5 days after admission, and parameters of diastolic function was evaluated. RESULTS: Echocardiographic data showed significant differences in mean ejection fraction, mean left ventricular mass, and mean left ventricular mass index between two groups. There was no significant difference in E/A ratio, deceleration time, and isovolumetric relaxation time between two groups. Neither, there was significant difference in each diastolic parameter for infarct related wall on EKG. And there was no significant difference in deceleration time for one or multi vessel disease on coronary angiography, treatment modality(conservative treatment, thrombolytic therapy, or primary PTCA). CONCLUSION: In patients with early acute myocardial infarction, left ventricular diastolic dysfunction was absent. And there was no significant correlation between the presence of diastolic dysfunction and the location of infarct related wall on EKG, or one or multi vessel disease, or treatment modality.
