“…They demonstrated a statistically significant dependency for sinus rhythm, atrial fibrillation, ventricular tachycardia atrioventricular blocks. As a result of their research, Ahmadi et al [14] included right His bundle branch block and ventricular tachycardia in the group of myocardial infarction risk factors. Our research into 12-lead ECG results found sinus rhythm OR=2.860 (CI 95%) and additional ventricular beats OR= 9.120 (CI 95%) to be significant predictors of myocardial infarction.…”

Background: Identifying predictive factors based on procedures carried out by emergency medical teams may speed up the diagnosis of AMI. By shortening the time between the onset of the pain and the initiation of coronary reperfusion, patient prognosis can be improved Methods: The study was conducted on residents of the Bielsko-Biała district, served by state ambulance service Medical Response Teams (MRT). The patients were assigned to the following groups: Group A (n = 338) - patients with chest pain in whom infarction with elevation of the ST segment (ST-ACS) was diagnosed on the basis of an ECG, Group B (n=300) - patients with chest pain in whom an infarction was not diagnosed. A factor structural test for the studied parameters was used to determine their significance. An odds ratio (OR) was established for statistically significant parameters, and multi-dimensional logistic regression analysis was conducted. The significance of the odds ratios (OR) was estimated for individual risk factors based on 95% confidence intervals (CI). Results: It can be stated with 95% probability that the significant parameters: Male (p=0.00001), Age 51-70(p=0.00307), Breathing rate less than 12/min(p=0.02711), Pulse below 60 min (p=0.00165), Edemas (p=0.00075), Moist skin(p<0.01), Sinus rhythm (p=0.00004), Additional ventricular beats(p=0.00133) increase the risk of myocardial infraction. Conclusion: Identifying the predictors of myocardial infarction specific to pre-hospital emergency care is essential for improving the detection of AMI and shortening the time between calls to the MRT and the initiation of coronary reperfusion.

“…In the present study, the mortality rate of patients was lower than those of some previous studies in Iran and higher than those of some others performed worldwide. An epidemiologic study on 20,750 patients with acute MI reported a general mortality rate of 12.1%, while about 85% of deaths were related to patients with STEMI [26]. Another study also reported a mortality rate of 13.2% for MI, with significantly worse outcomes in patients with STEMI [27].The mortality rates reported in these studies, although similar to that of the thrombolytic group, cannot be compared with those of the current study, since they did not report the rates based on the type of MI (STEMI vs. non-STEMI) or the treatments received.…”

“…Donyavi et al, reported a mortality rate of 24.6% after acute MI in Iranian patients [28], which was higher than the mortality rates of both groups in the present study, although they did not separate the rates based on the type of disease. An important findings of these studies indicated that the socio-demographic characteristics of patients, type of MI, and the concomitant diseases played a fundamental role in the mortality rate [26][27][28], which could also attribute to the difference in the reported mortality rates. One of the limitations of the present study was the nonrandom inclusion of patients into the study and selection of patients from one center, which decreased the generalizability of the results, although the study site was a tertiary center in the city center with high patient load.…”

Introduction: The ischemic time serves as the most important parameter for treatment choice in patients with ST-elevation myocardial infarction (STEMI). The current study aimed at comparing the short-and long-term follow-up of elderly patients with STEMI undergoing primary angioplasty (PCI) or thrombolytic therapy. Methods: The current cross sectional study was conducted on all patients aged > 65 years, admitted to the emergency department of Imam Hossein Hospital, Tehran, Iran from January 2014 to July 2016, diagnosed with STEMI. The demographics, medical history, family history, and mediation history were recorded for all patients. Patients received PCI or thrombolytic therapy based on the ischemic time and the treatment outcome and the following events were recorded. Patients were contacted after six months and data of their death or used treatments were recorded. All data were compared between the groups. Results: Of all patients, 38 subjects received thrombolytic therapy and 62 PCI. There was no significant difference between the groups in terms of mean age and gender (P = 0.5 and 0.1, respectively). The frequency of positive medical history and smoking did not differ between the groups. There was no difference in the mean values of vital signs or serum parameters, mean ischemic time, left ventricular ejection fraction (LVEF), frequency of pulmonary emboli, cardiogenic shock, the involved vessel, and posttreatment complications between the groups (P > 0.05). Of the 14 cases that died after six months, five were in the thrombolytic therapy group and nine in the PCI group (P = 0.8). Mean hospital stay was not different between the groups (P = 0.5). Conclusions:The results of the present study on two groups with similar demographics showed no significant difference between the groups in terms of the short-and long-term follow-up of PCI and thrombolytic therapy. The results indicated the appropriateness of treatment choice based on ischemic time and the available methods.

“…Thus, among the smoking female, the age of death occurs about 14.5 years earlier and in the case of men, smokers die 13.2 years earlier thannonsmokers [13,14]. It is estimated that smoking is responsible for about 10% of all cardiovascular deaths [15].Cessation of smoking is the most important intervention in preventive cardiology.After an acute coronary event, quitting smoking reduces cardiovascular mortality by 36% [15].…”

The prevalence of coronary artery disease, a major contributor to cardiovascular disease, is related to the increasing prevalence of modifiable risk factors.The aim of our study was to determine the risk factors for acute myocardial infarction among patients from North East Romania.We evaluated patients with acute myocardial infarction with or without left bundle-branch block, hospitalized in Georgescu Institute of Cardiovascular Disease Iasi for three years. The results of our study show that patients with acute myocardial infarction and new left bundle branch block have a more recent history of hypertension, dyslipidemia and smoker status compared to patients without left bundle branch block. Nearly two thirds of patients included in the study (65.47%) had an elevated cholesterol level, with a high prevalence of dyslipidemia in patients with myocardial infarction and new left bundle branch block. More than two-thirds of patients with new left bundle branch block had a history of arterial hypertension (69.04% vs. 50.0%, p = 0.354), especially grade 2 hypertension, with a slight predominance in those with new left bundle branch block, but without statistically significant differences between the two groups (45.23% vs. 30.95%, p = 0.358). Early identification of modifiable risk factors is vital to set the strategy for prevention and special attention must be paid to smoking. An adequate control of cardiovascular risk factors would result in a significant reduction of coronary events in patients from the North East part of Romania.

Epidemiological pattern of myocardial infarction and modelling risk factors relevant to in-hospital mortality: the first results from the Iranian Myocardial Infarction Registry

Abstract: STEMI, lack of thrombolytic therapy, age of over 84 years, and ventricular tachycardia have the greatest effect on in-hospital mortality in MI patients. The results of this study are helpful in planning for monitoring and promotion of healthcare of the patients.
