Abstract
Aim: To evaluate the relationship between clinical severity of unstable angina (according to Braunwald 24 classification), along with coronary angiographic profile.
Methods: 60 unstable angina patients (both male and female) who had undergone coronary angiogram, fulfilling the inclusion and exclusion criteria.
Results: Out of 60 patients 50 were males and 10 were females. Age ranged from 35 to 70 years with the mean value 52.6±9.2. Among risk factors, prevalence of smoking and dyslipidaemia were found significantly higher (86.7% and 93.3% respectively) in class IIIB in comparison to other classes (p<0.05). Other risk factors did not bear any significant association (p>0.05). We compared morphology of lesion among the groups. In class IB-80% of cases had type A morphological lesion, where as in class IIB 56% had type B lesion. Class IIIB and class C had 73.3% type C and 80% type B lesion respectively. We found simple lesion in 27 subjects (45%). Among them concentric type lesion was found in 9 patients and eccentric type lesion was found in 18 patients. We found complex lesions (eccentric, irregularity) in 33 subjects. Triple vessel diseases were common in class C and class IIIB. In LCA and in RCA showed advanced angina pain group (class IIB, IIIB and class C) had greater number of 10-20 mm long lesions.
Conclusion: Unstable angina patients often harbor multiple complex coronary lesions and importantly the more the complex plaques the worse the prognosis. Coronary angiography guides us as to which patient needs urgent angiographic evaluation and treatment.
