Coronary artery disease pattern in the young
Insights
Young patients with coronary artery disease often have significant vessel disease and abnormal heart function. Risk factors strongly correlate with the severity of coronary artery disease in this demographic.
Area of Science:
- Cardiology
- Vascular Medicine
- Preventive Cardiology
Background:
- Coronary artery disease (CAD) typically affects older individuals.
- Early-onset CAD in patients under 40 presents unique challenges.
- Understanding risk factors and disease patterns in young CAD patients is crucial.
Purpose of the Study:
- To investigate risk factors, angiographic findings, and left ventricular function in patients younger than 40 with CAD.
- To determine the relationship between risk factors and the extent of coronary artery disease in young adults.
Main Methods:
- Retrospective analysis of 92 patients aged 40 or less with documented coronary artery disease.
- Assessment of cardiovascular risk factors, including tobacco use and family history.
- Coronary angiography to evaluate vessel involvement and left ventricular function (ejection fraction, end-diastolic pressure).
Main Results:
- Tobacco consumption (54%) and family history (40%) were the most prevalent risk factors.
- Multi-vessel coronary artery disease was more common than single-vessel disease.
- Abnormal left ventricular function (ejection fraction) was observed in 51% of patients.
- A positive association was found between the presence of risk factors and significant CAD.
Conclusions:
- Young patients with coronary artery disease exhibit a high prevalence of multi-vessel involvement and impaired left ventricular function.
- Tobacco use and family history are significant risk factors in this population.
- The presence of risk factors is linked to more severe coronary artery disease in younger individuals, highlighting the importance of early detection and intervention.
Abstract:
Ninety-two patients aged 40 years or less with documented coronary artery disease were studied with special emphasis on risk factors, coronary angiographic patterns and left ventricular function. Tobacco consumption was the most common risk factor (54%) followed by family history of coronary artery disease (40%). Hyperlipidaemia was not a frequent risk factor. Significant single vessel disease was present in 29% of patients. The incidence of double vessel and triple vessel disease was much higher. The left anterior descending artery was the most commonly involved vessel followed by right and circumflex coronary arteries. Left ventricular function as determined by ejection fraction was abnormal in 51% of patients; left ventricular end diastolic pressure was abnormal in 28% of patients. Sixty-eight percent of patients with no risk factors had either zero vessel or single vessel disease indicating a positive relationship between occurrence of risk factors and significant coronary artery disease in the young.
