The authors discuss the case of a young woman, with chest pain at rest and normal coronary arteries. Sixty-three days after the onset of the symptoms the patient had a myocardial infarction. The coronariogram showed obstruction of the left coronary artery in its full length. The authors consider that a coronary spasm was the cause of the infarction. It is very likely that independent of personal characteristics, coronary spasm may be persistent, involve the whole extent of the vessel and occur even with use of vasodilator drugs.

The guide extension-facilitated ostial stenting (GEST) technique uses a guide extension catheter (GEC) to improve stent delivery during primary coronary angioplasty (PCI). GECs are used for stent delivery into the coronary arteries of patients with difficult anatomy due to tortuosity, calcification, or chronic total occlusion (CTO) vessels. Stent and balloon placement has become challenging in patients with increasing lesion complexity due to tortuosity, vessel morphology, length of the lesion, and respiratory movements.

Background: The left internal thoracic artery (LITA) has been widely accepted as the standard for revascularizing the left anterior descending artery during coronary artery bypass grafting (CABG) surgery. However, in 10-20% of cases, the LITA may lead to unsecured side branches to the chest wall, particularly the lateral costal artery (LCA), potentially resulting in postoperative chest angina.
Case Presentation: We report the case of a 58-year-old patient who experienced persistent angina eight months after having undergone coronary artery bypass grafting (CABG) due to the steal phenomenon caused by a thick lateral costal artery (LCA).

Background: The outcome of coronary artery bypass grafting (CABG) depends on several factors, including the quality of the distal anastomoses to the coronary arteries. Early graft failure may be caused by, e.g.

Although the relationships between basic clinical parameters and white matter hyperintensity (WMH) have been studied, the associations between vascular factors and WMH volume in general populations remain unclear. We investigated the associations between clinical parameters including comprehensive vascular factors and WMH in two large general populations. This retrospective, cross-sectional study involved two populations: individuals who underwent general health examinations at the Asan Medical Center (AMC) and participants from a regional cohort, the Korean Genome and Epidemiology Study (KoGES).

Background: Cardiovascular disease (CVD) is a leading cause of death in ANCA-associated vasculitis (AAV). Screening and primary cardiovascular prevention may improve outcomes.
Methods: We identified patients in the 2002-2019 Mass General Brigham AAV cohort with thoracic CT scans obtained for other clinical purposes.
