Prevalence of obstructive coronary artery disease in patients with and without prior stroke undergoing coronary angiography for suspected coronary artery disease.
This study was conducted to investigate the prevalence and severity of obstructive coronary artery disease (CAD) in 64 men and 38 women (mean age 71+/-9 years) with previous stroke and in 102 age- and gender-matched patients with similar coronary risk factors without previous stroke who underwent coronary angiography for chest pain. Obstructive CAD was present in 100 of 102 patients (98%) with previous stroke and in 84 of 102 (82%) patients without previous stroke (p<0.001). Obstructive 3-vessel CAD was present in 56 of 102 patients (55%) with previous stroke and in 35 of 102 patients (34%) without previous stroke (p<0.005). The prevalence of 2-vessel CAD and of 1-vessel CAD was not significantly different between patients with and without previous stroke. In conclusion, patients with previous stroke have a significantly higher prevalence of obstructive CAD and of obstructive 3-vessel CAD than age- and gender-matched patients with similar coronary risk factors without previous stroke who undergo coronary angiography for chest pain.
