What factors are associated with long-term prognosis of vasospastic angina treated with calcium channel antagonists?
The severity of the lesion and hypercholesterolemia are the two main factors associated with long-term prognosis of vasospastic angina treated with calcium channel antagonists, according to a study done by Yamagishi et al. (2003). It found that patients with severe lesions and higher levels of cholesterol had worse prognoses than those with milder lesions and lower cholesterol levels. Additionally, smoking is also known to be a risk factor for coronary spasm (Sugiishi & Takatsu, 1993; Nobuyoshi et al., 1992).
