Incidence and Implications of J waves Observed During Coronary Angiography
Section snippets
Results
The patients’ clinical characteristics are listed in Table 1. The mean age was 68.3 ± 14.1 years, and 87% of participants were men. In the majority of cases, angiography was performed to evaluate previous percutaneous coronary intervention for acute myocardial infarction or angina pectoris. A total of 11 patients underwent CAG before transaortic valve replacement. Comorbidities were controlled by medication and no patient complained of chest pain or distress during CAG. Including the patients
Discussion
We investigated the incidence of CAG-induced J waves or augmentation of J waves in 100 consecutive patients who underwent CAG. The majority had undergone stenting for angina pectoris or myocardial infarction, but none had significant stenosis in the right coronary artery, including the stenting site, at the time of this study. Nonischemic heart diseases included idiopathic cardiomyopathy and valvular heart disease. In inferior leads, new J waves or augmentation of the J-wave amplitude was
