Recent data suggest that CCTA may play a role in higher risk patients, such as those evaluated in the emergency room with acute chest pain. Data thus far support the use of CCTA in low-risk patients with acute chest pain. Recent literature suggests that CCTA may play a role in the risk stratification of selected intermediate-risk patients. In this review, the authors discuss the emerging role of CCTA in higher risk patients, such as those with suspected or confirmed acute coronary syndrome (ACS). The excellent accuracy of CCTA in detecting obstructive coronary artery disease in patients with ACS is detailed, along with a highlighting of the safety of using CCTA in this setting. The authors also discuss the role for CCTA atheromatous plaque characterization, which is being increasingly recognized as an important predictor of clinical outcomes.</p>","PeriodicalId":93393,"journal":{"name":"US cardiology","volume":"16 ","pages":"e11"},"PeriodicalIF":0.0,"publicationDate":"2022-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11588185/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142735259","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Younger patients theoretically benefit the most from closure due to longer lifetime exposure risk and absence of other traditional risk factors. PFO in older patients with cryptogenic strokes is often encountered in clinical practice, making up an increasing number of cardiology referrals, yet cardiologists lack guidelines and evaluation tools for these patients.

It is crucial for operators to recognize potential vascular complications associated with radial artery access. Prevention, early detection, and prompt treatment of vascular complications are essential to prevent serious morbidities. This review aims to raise awareness of transradial access vascular complications. Radial artery spasm is treated with intra-arterial verapamil and/or nitroglycerine. Hemorrhagic complications, such as perforation, hematoma, arteriovenous fistula, and pseudoaneurysm, are treated with prolonged compression. Patent hemostasis and adequate anticoagulation are used to prevent radial artery occlusion. Hand ischemia is a rare complication not associated with abnormal results of the Allen or Barbeau test, and can be treated with intraarterial verapamil, IV heparin, and IV diltiazem.
