“…Previously, epicardial coronary dilation has been suggested to exacerbate myocardial ischemia [2] and are discouraged in patients with isolated CAE. Although the data reported by Kim et al [1] have shown that coronary vasodilators as nitrate and nicorandil have no detrimental effect on coronary blood flow, the small sample size (only 10 patients with isolated coronary artery ectasia) limits extrapolation of these findings to all patients with isolated CAE.…”

“…I have recently read with great interest an important article published in International Journal of Cardiology entitled "The changes of fractional flow reserve (FFR) after intracoronary nitrate and nicorandil injection in coronary artery ectasia (CAE)" [1]. In this article, Kim et al [1] have evaluated FFR in patients with isolated CAE in response to intracoronary nitrate and nicorandil injection.…”

“…Furthermore, acute coronary syndromes may also develop in these patients despite the absence of any obstructive coronary lesion. Similarly, all patients included in Kim et al [1] study admitted to the hospital with unstable angina pectoris. Myocardial ischemia have been attributed to the in-situ thrombosis within the ectasic segment and distal microembolisation of in-situ thrombi.…”

The purpose of the present study was to clarify the possible relationship between nitroglycerin (NTG)-induced headache and both vascular functional and organic atherosclerosis. The study included 96 patients with NTG-induced headache (group I: 54.7±9.5 years, 52 males) and 204 patients without headache (group II: 58.1±9.1 years, 127 males) who suffered from new-onset chest pain. Flow-mediated dilation and nitroglycerin-mediated dilation were significantly greater in group I than in group II (8.8±4.1% vs. 7.1±3.5%, p=0.001, and 23.1±7.3% vs. 17.1±11.8%, p<0.001, respectively). The carotid intima-media thickness was significantly smaller in group I than in group II (0.55±0.15 mm vs. 0.67±0.22 mm, p=0.001). Heart-carotid pulse wave velocity was significantly lower in group I than in group II (784.5±160.1 m/s vs. 979.1±215.6 m/s, p=0.003). In the multiple regression analysis, the absence of NTG-induced headache was a predictor of coronary artery disease (CAD) (odds ratio: 17.89, 95% confidence interval: 7.89-40.02, p<0.001). NTG-induced headache developed more frequently in patients with normal coronary arteries or minimal CAD than in patients with obstructive CAD. The presence of NTG-induced headache might be helpful and provide additional information in evaluating patients with chest pain syndrome.
