“…These are the well developed risk factors of ACS and lead to interrupted supply of oxygen to the myocardium. [12][13][14] As we already know that the every cell of myocardium has the potential to become a pacemaker. So, the cases with these risk factors especially those with having combination of these had more severe form of disease and hence led to increased number of this complication to develop.…”

Chest pain is one of the most common presentations to the emergency and cardiology clinics and most serious of these is acute coronary syndrome (ACS) is a life threatening acute emergency. 1 There are a number of complications, which can cause death immediately in patients of ACS which include arrhythmias, cardiogenic shock, progressive heart failure, mechanical cardiac complications and repeat MI. 2-3 Objectives: To determine the frequency of different arrhythmias in patients with acute coronary artery syndrome in the first 24 hours of hospitalization.

Introduction: Chest pain is one of the most common presentations to theemergency and cardiology clinics and most serious of these is acute coronary syndrome (ACS)is a life threatening acute emergency.1 There are a number of complications, which can causedeath immediately in patients of ACS which include arrhythmias, cardiogenic shock, progressiveheart failure, mechanical cardiac complications and repeat MI.2-3 Objectives: To determine thefrequency of different arrhythmias in patients with acute coronary artery syndrome in the first24 hours of hospitalization. Study Design: Cross sectional study. Period: 1st July 2016 to 31stJanuary 2017. Setting: Department of Cardiology, Sheikh Zayed Medical College/Hospital,Rahim Yar Khan. Methodology: 379 consecutive cases of ACS of either gender, with age rangeof 30 to 60 years were included. Socio-demographic data and other clinical data was taken.These patients were then attached with ECG monitors in department of cardiology, and ECGwas recorded for 24 hours and then the type of arrhythmias if detected (PVCs / AF / VF / nonsustained VT / sustained VT / first degree heart block/ second degree heart block/ third degree)and duration of develop arrhythmias was noted according to operational definitions. Results: Inthis study there were total 379 cases out of which 193 (50.92%) were males and 186 (49.08%)females with mean age of 48.80±4.51 years. Arrhythmias were detected in 175 (46.17%) cases.The most common arrhythmia was PVCs seen in 44 (11.61%) out of 379 cases. Arrhythmiasaffected more to age groups 30-45 years affecting 66 (58.9%) cases with p= 0.002 and thosewith BMI more than 30 (p= 0.01). The cases with DM and NSTEMI had it more with p= 0.02and 0.01 respectively. On stratification of different types of arrhythmia, the male gender wassignificantly associated with sustained VT and female with second degree HEART BLOCK. Theage group of 46-60 years was significantly associated with AF and sustained VT. Regardingdifferent type of ACS, NSTEMI as compared to STEMI was found significantly associatedwith VF, non-sustained VT, sustained VT and third degree heart block with p= 0.0001, 0.02,0.01 and 0.001. Conclusion: Acute coronary syndrome with arrhythmia is a well-encounteredcomplication presenting to the chest pain and coronary care units. Age group 30-45, higherBMI, and DM have significant association with different types of arrhythmias seen in patientsadmitted with ACS and PVC is the most common arrhythmia seen in ACS.

“…Arrhythmias and conduction abnormalities are common complications of AMI, which are a major cause of death within the first 3 days in AMI [1][2][3][4] . It's primarily a consequence of heightened adrenergic nervous system tone, ischemia and myocardial necrosis, hypokalemia, hypomagnesemia, intracellular hypercalcemia, acidosis, free fatty acid production from lipolysis, and increased free radical production from reperfused ischemic myocardium ( Figure 1) 5,6 .…”

Öz Purpose: Arrhythmias and conduction disturbances are common during acute myocardial infarction (AMI) and a major cause of death in the pre-hospital phase. The aim of this study was to investigate common predictors for all arrhythmias in patients with ST elevation AMI (STEMI) during in-hospital phase. Materials and Methods: Ninety patients (74 male, 55 ±11 years) with acute STEMI were included. Clinical charesteristics were recorded and laboratory parameters including serum C-reactive protein (CRP), creatinine kinase MB (CKMB) and potassium levels were measured. The patients were divided into two groups according to development of arrhythmias. Results: Group 1 (n=42) patients had new onset arrhythmias and Group 2 (n=48) patients had without arrhythmias. Median baseline CRP levels were significantly higher in group 1 (36.6 (21.8-77) mg/dl vs. 21.8 (24.2-30.7) mg/dl), especially in patients with atrial fibrillation and ventricular arrhythmias. Logistic regression analysis showed that baseline higher CRP level, peak CKMB level and inferior localization of AMI were significantly associated with the development of arrhythmia following AMI. Conclusion: Levels of CRP and CKMB and inferior infarct localization have predictive values for all the arrhythmic events during AMI. CRP levels were found to be associated with both atrial and ventricular arrhythmias. The assessment of CRP levels can be used to detect patients at high risk for arrhythmic events after STEMI.

Bundle branch and atrioventricular block as complications of acute myocardial infarction in the thrombolytic era

Abstract: During the current era of thrombolytic therapy and in this population, intraventricular disturbances of electrical conduction and complete atrioventricular block were associated with a high and independent risk of inhospital death during acute myocardial infarction.
