Insights
Cardiac catheterization in Qatar, initiated in 1982, involved 3900 procedures over ten years. Analysis revealed younger patients often had recent myocardial infarction and single-vessel disease, particularly those of Asian origin.
Area of Science:
- Cardiology
- Interventional Cardiology
- Public Health
Background:
- Cardiac catheterization services in Qatar commenced in July 1982.
- Hamad General Hospital performed 3900 procedures over the first decade.
- A computerized registry has documented data since 1982.
Purpose of the Study:
- To analyze the trends and outcomes of cardiac catheterization procedures in Qatar.
- To compare the demographic and angiographic characteristics of younger versus older patients undergoing coronary angiography.
- To identify patterns in coronary artery disease among different patient groups.
Main Methods:
- Retrospective analysis of 2911 isolated coronary angiographies performed between 1982 and 1992.
- Data collected from a computerized registry at Hamad General Hospital.
- Comparison of angiographic findings between patients aged 40 years or younger and older patients.
Main Results:
- Myocardial infarction was the primary indication for angiography (43%).
- Prevalence of coronary artery disease included single-vessel (22%), two-vessel (22%), three-vessel (33%), and nonsignificant disease (24%).
- Younger patients (≤40 years, 28%) were predominantly Asian males with recent myocardial infarction, often presenting with normal or single-vessel disease.
Conclusions:
- Cardiac catheterization in Qatar has a low morbidity rate (5%) with no reported mortality.
- Younger patients undergoing angiography exhibit distinct demographic and etiological profiles compared to older patients.
- Asian subcontinent males represent a significant demographic undergoing angiography for recent myocardial infarction, frequently with less severe coronary artery disease.
Abstract:
Cardiac catheterization in Qatar was initiated in July 1982. In ten years, a total of 3900 procedures were performed at Hamad General Hospital. Computerized data registry has been maintained since 1982. Isolated coronary angiography was done in 2911 patients; of these, 2635 (90.5%) were men, and 276 (9.5%) were women, the average age of the patients was 47+/-9.2 years (range, twenty-five to eighty-eight). Patients' nationality was Qatari in 492 (17%), and other Arabs in 610 (21%), and 1512 (52%) were from the Asian subcontinent. Myocardial infarction was the most common indication (43%). Single-vessel disease was found in 638 (22%), two-vessel disease in 630 (22%), three-vessel disease in 950 (33%), and nonsignificant coronary artery disease in 693 (24%) patients. Morbidity related to the coronary angiography was reported in 147 (5%) patients, but there was no mortality related to the procedure. In 822 (28%) patients, the age was forty years or younger. The angiographic findings of these younger patients were compared with those of the older ones. Younger patients were usually men of Asian subcontinental origin with a recent myocardial infarction (MI). Often, they had normal coronary arteries or single-vessel disease. Patients of Asian subcontinent origin were usually young male patients with a recent MI, who receive streptokinase, and have single-vessel disease.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
