Insights
This study analyzed the characteristics and outcomes of Internal Cardioverter Defibrillator (ICD) therapy in Saudi Arabia. Saudi patients receiving ICDs were younger with more risk factors than Western counterparts, showing a low mortality rate.
Area of Science:
- Cardiology
- Medical Devices
- Public Health
Background:
- Internal Cardioverter Defibrillators (ICD) reduce mortality in high-risk patients.
- No prior data existed on ICD patient characteristics and outcomes in Saudi Arabia.
- This study addresses the need for local data on ICD therapy.
Purpose of the Study:
- To investigate the clinical features of patients undergoing ICD implantation in Saudi Arabia.
- To evaluate the outcomes of ICD therapy in this population.
- To compare Saudi ICD patient demographics and risk factors with international data.
Main Methods:
- Retrospective analysis of 108 patients who received ICDs at King Khalid University Hospital.
- Data collected from November 2007 to January 2010.
- Follow-up averaged 18 months.
Main Results:
- The mean age was 58.6 years; 87% were male.
- High prevalence of comorbidities: 58.3% Diabetes Mellitus, 61.1% Hypertension, 63% smokers.
- Mean ejection fraction was 24.5%; 83.3% received ICDs for primary prevention.
- Low mortality rate of 3.7% over 18 months.
Conclusions:
- This is the first study detailing ICD patient characteristics and outcomes in Saudi Arabia.
- Saudi patients receiving ICDs are younger with a higher prevalence of risk factors compared to Western populations.
- ICD therapy demonstrated favorable outcomes in this cohort.
Introduction:
Internal Cardioverter Defibrillators (ICD) has been shown to decrease mortality in patients such as those with structural heart disease or at high risk of sudden cardiac death. To date there is no data regarding the clinical features, and outcomes of ICD patients in Saudi Arabia. Accordingly, we explored the clinical features and outcomes of ICD therapy among Saudis.
Methods:
Patients who had ICD implantation in King Khalid University Hospital from November 2007 until January 2010 were enrolled.
Results:
One hundred and eight ICD were implanted between November 2007 and February 2010. The mean age was 58.6±13.2 years. The majority were male 94 (87%), the rate of Diabetes Mellitus (DM) was 58.3%, Hypertension (HTN) was 61.1%, and 63% were smokers. The mean ejection fraction (EF) was 24.5%. Of the 108 patient 90(83.3%) had ICD insertion for primary prevention and 18(16.7%) for secondary prevention. Of the 90 patients who ICD for primary prevention 62 (57.4%) had ischemic cardiomyopathy, 39(36.1%) had dilated cardiomyopathy and 7 (6.5%) had channelopathy. Over a mean follow-up of 18 months 4 (3.7%) died.
Conclusions:
Our study describes for the first time patients characteristic and outcomes for ICD therapy in Saudi Arabia. Our patients are younger and have higher prevalence of risk factors that those in Western countries.
