Acute Coronary Syndromes

Acute coronary syndrome (ACS) is most commonly caused by a heart attack (myocardial infarction) where blood flow to the heart is suddenly blocked. This is usually caused by a blood clot from a ruptured coronary artery atherosclerotic plaque. Other causes include spontaneous coronary artery dissection (SCAD), which most commonly occurs in women. ACS is usually treated in a cath lab with angioplasty and the placement of a stent to prop the vessel open.

Predicting sudden cardiac death after a heart attack may be impossible—for now

Researchers tried to crack the code, but they fell short time and time again. AI may offer potential as one way to finally find an answer, they added.

Payment cuts and beyond: Key takeaways for cardiologists from the 2025 Medicare Physician Fee Schedule

The American College of Cardiology has shared its perspective on new CMS payment policies, highlighting revenue concerns while providing key details for cardiologists and other cardiology professionals. 

‘A huge win’: CMS significantly increases Medicare payments for cardiac CT

CMS has more than doubled the CCTA payment rate from $175 to $357.13. The move, expected to have a significant impact on the utilization of cardiac CT, received immediate praise from imaging specialists.

HeartLung Technologies, a Houston-based artificial intelligence (AI) company, has received 510(k) clearance from the U.S. Food and Drug Administration (FDA) for new software that assesses chest CT scans for signs of coronary artery disease (CAD) and other potentially fatal heart conditions. The newly cleared offering, AutoChamber, was designed with opportunistic heart evaluations in mind.

FDA clears AI tool that flags signs of heart disease in chest CT scans

The newly cleared offering, AutoChamber, was designed with opportunistic screening in mind. It can evaluate many different kinds of CT images, including those originally gathered to screen patients for lung cancer.

Colchicine falls flat in large heart attack trial, convincing cardiologists to stay away

Treating AMI patients with colchicine is not associated with better cardiovascular outcomes, according to new data presented at TCT. The drug did help with inflammation, but that was the only benefit researchers could identify.

New data highlight long-term benefits of HeartFlow’s AI-based CAD evaluations

HeartFlow kicked off TCT 2024 by sharing new research on the long-term impact of its FFRCT Analysis and Plaque Analysis software.

Medicare coverage expands again for AI-enabled coronary plaque assessments

Another MAC has agreed to cover the use of these advanced technologies to evaluate patients for signs of coronary artery disease. 

The Shockwave Medical M5+ new peripheral intravascular lithotripsy (IVL) catheter cuts procedures times in half and was showed for the first time at the American College of Cardiology (ACC) 2022 meeting. It is designed to break up calcium in heavily calcified arteries to avoid the need for vessel trauma caused by high pressure angioplasty.

IVL vs. RA for chronic total occlusion PCI: Key data cardiologists should know

Patient outcomes for these two treatments are similar, but choosing IVL may help improve clinical workflows. 

Around the web

Several key trends were evident at the Radiological Society of North America 2024 meeting, including new CT and MR technology and evolving adoption of artificial intelligence.

Ron Blankstein, MD, professor of radiology, Harvard Medical School, explains the use of artificial intelligence to detect heart disease in non-cardiac CT exams.
