Evaluating Mortality Rate and Associated Parameters in Patients with Acute Coronary Syndrome

Complications in Emergency Department Patients with Acute Coronary Syndrome with Contemporary Care

INTRODUCTION

With the implementation of early reperfusion therapy, the number of complications in patients with acute coronary syndrome (ACS) has diminished significantly. However, ACS patients are still routinely admitted to units with high-level monitoring such as the coronary or intensive care unit (CCU/ICU). The cost of these admissions is high and there is often a shortage of beds. The aim of this study was to analyze the complications in contemporary emergency department (ED) patients with ACS and to map patient management.

METHODS

This observational study was a secondary analysis of data collected in the ESC-TROP trial (NCT03421873) that included 26,545 consecutive chest pain patients ≥18 years at five Swedish EDs. Complications were defined as the following within 30 days: death, cardiac arrest, cardiogenic shock, pulmonary edema, severe ventricular arrhythmia, high-degree atrioventricular (AV) block that required a pacemaker, and mechanical complications such as papillary muscle rupture, cardiac tamponade, or ventricular septum defects (VSDs). Complications were identified via diagnosis and/or intervention codes in the database, and manual chart review was performed in cases with complications.

RESULTS

Of all 26,545 patients, 2,463 (9.3%) were diagnosed with ACS, and 151 of these (6.1%) suffered any complication within 30 days. Mean age was higher in patients with (79.2 years) than without (69.4 years) complications, and more were female (39.7% vs. 33.0%). Eighty-four (3.4% of all ACS patients) patients died, 33 (1.3%) had cardiac arrest, 22 (0.9%) respiratory failure, 13 (0.5%) high-degree AV block, 10 (0.4%) cardiogenic shock, 12 (0.5%) severe ventricular arrhythmia, and 2 each (<0.1%) had VSD or cardiac tamponade. Almost 30% of the complications were present already at the ED, and 40% of patients with complications were not admitted to the CCU/ICU. Only 80 (53%) of the patients with complications underwent coronary angiography and 62 (41%) were revascularized with percutaneous coronary intervention or coronary artery bypass grafting.

CONCLUSION

With current care, serious complications occurred in only 6 out of 100 ACS patients, and 2 of these complications were present already at the ED. Four out of 10 ACS patients with complications were not admitted to the CCU/ICU and about half did not undergo coronary angiography. Further research is needed to improve risk assessment in ED ACS patients, which may allow more effective use of cardiac monitoring and hospital resources.

Frequency of recurrence of peripheral artery disease among angioplasty and stenting patients

Background

Peripheral artery disease (PAD) is a cardiovascular disease that is characterized by obstruction of peripheral artery. It is associated with comorbidities, reduced quality of life and mortality. The aim of this study was to determine the frequency of recurrence of PAD among patients who underwent angioplasty or stenting and associated risk factors.

Methods

In this retrospective study, all patients referred to the cardiovascular center of (XXX) with the diagnosis of lower extremity PAD were included. Patients’ demographic information, age, gender, smoking status, history of diabetes, history of hypertension, dyslipidemia, number of vessels, type of stent, recurrence of the disease, and size of the lesion were obtained from the hospital database. Endovascular revascularization therapy was either performed by angioplasty or stenting method. The data were analyzed by SPSS v21.

Results

Of 88 patients included in this study, 12.5% were reported with restenosis. Gender, age, size of the lesion, the status of smoking, history of hypertension, and dyslipidemia were not significantly associated with the recurrence of stenosis, p > 0.05. There was a significant relationship between the vessels involved and the type of revascularization method and the recurrence of the PAD.

Conclusion

Endovascular revascularization technique and type of vessel involved in PAD are significant factors contributing to restenosis in our population of study. However, further studies with a greater sample size are required in this area.

•

Peripheral artery disease is a cardiovascular disease with obstruction of peripheral artery.

•

It is associated with comorbidities, reduced quality of life and even mortality.

•

Endovascular revascularization technique in PAD are significant factor in our study.

•

However, further studies with greater sample size are required in this area.

Frequency of Cardiac Arrhythmias in Children with Cardiological Consulting and Containing Electrocardiogram

BACKGROUND

Heart diseases are the leading causes of mortality and congenital heart disease (CHD) is the most common birth defect reported worldwide.

OBJECTIVE

The aim of this study was to evaluate the incidence of arrhythmias and CHD and the association between the two, among infants and children reported to our center.

METHODS

This cross-sectional study included infants and children who were referred to Shahid Madani Hospital, Khorramabad. Electrocardiogram (ECG) was performed in these children to determine the type of arrhythmia and records were used to obtain demographic data and the data regarding CHD.

RESULTS

Of 200 children enrolled in the study, 10 children had arrhythmias, 12 had tachycardia, 5 had bradycardia, and 31 had congenital disease. Among children with arrhythmias, 1 had atrial fibrillation, 4 patients had paroxysmal supraventricular tachycardia, 1 person had right bundle branch block, 1 had ventricular tachycardia, 2 had premature ventricular contractions and 1 had junctional ectopic tachycardia. Of the 31 children with CHD, 9 patients were presented with small ventricular septal defect, 4 children had patent foramen ovale, 2 had pulmonary stenosis and 1 of the children had tetralogy of fallout, arterial and ventricular septal defects and transposition of greater arteries, respectively.

CONCLUSION

We reported a positive correlation between the arrhythmias and CHD. A larger number of studies collecting focusing on different age groups are therefore required to verify our findings.

Prevalence of Congenital Heart Disease among Children in Khorramabad (West of Iran)

AIMS

Congenital heart disease is among the most common congenital anomalies in pediatrics. The aim of this study was to evaluate the prevalence of congenital heart disease in children in Khorramabad, Iran.

METHODS

This is a descriptive-cross sectional study where all the children diagnosed with congenital heart disease by echocardiography were enrolled to the Shahid Madani Hospital. Patient information was collected by means of a questionnaire. Of 1600 children who underwent cardiac counseling, 9.75% presented congenital heart disease. These were most prevalent among the children of 0-28 days of the age (14.7%) and least in children aged 1 month-1 year. According to this study, atrial (20.3%) and ventricular septal defect (10.5%) were the most common heart defects, respectively. Among signs and symptoms of cardiac disease, 49.1% of children had cyanosis, 89.7% with increased CT (cardiothoracic)-ratio, and 82.7% of had heart murmur. Congenital heart disease was more prevalent in male infants (58%) and 6.6% patients had heart failure and 1.4% had other congenital conditions, such as Down syndrome.

RESULTS

According to our findings, atrial and ventricular septal defects are the most common congenital heart anomalies, respectively, in pediatric patients in Khorramabad.
