Interventional Cardiology

This cardiac subspecialty uses minimally invasive, catheter-based technologies in a cath lab to diagnose and treat coronary artery disease (CAD). The main focus in on percutaneous coronary interventions (PCI) to revascularize patients with CAD that is causing blockages resulting in ischemia or myocardial infarction. PCI mainly consists of angioplasty and implanting stents. Interventional cardiology has greatly expanded in scope over recent years to include a number of transcatheter structural heart interventions.

Prolonged dual antiplatelet therapy regimen after PCI may benefit patients with PAD

A dual antiplatelet therapy regimen of up to 24 months was associated with a significantly lower risk of death, MI or cerebrovascular accidents in patients with peripheral artery disease (PAD) who underwent PCI.

Using beta-blockers after elective PCI does not improve cardiovascular outcomes in older adults

The use of beta-blockers in older adults with stable angina who underwent PCI did not reduce the adjusted mortality rate, MI, stroke or revascularization, according to retrospective, observational registry analysis.

Low diastolic blood pressure puts patients at greater risk

While blood pressure drugs have been successful at pushing patient’s systolic blood pressure down to 120—the recognized benchmark for a healthy blood pressure—they have also dropped diastolic blood pressure to potentially dangerous levels.

FDA approves new bolus vial form of tirofiban hydrochloride

The FDA approved a bolus vial form of tirofiban hydrochloride (Aggrastat) on Sept. 1.

Conjoined twins survive heart, liver separation surgeries

Advanced imaging technologies and techniques were used this summer to successfully separate two conjoined twin girls.

Google your way to better heart health

Googling symptoms to make a diagnosis is not medical best practice. But now, thanks to a collaborative effort between the American College of Cardiology and the world’s most popular search engine, Google searches for heart conditions will produce important questions patients should ask their doctors based on ACC clinical guidelines.

Drug-eluting stents, bare-metal stents have similar rates of death, nonfatal spontaneous MI at 6 years

Millions of patients each year undergoing PCI are implanted with drug-eluting or bare-metal stents. Comparisons between the types of stents have been limited, although a recent randomized study in Norway showed similar outcomes between the two categories.

Cost, biological pathways limit cardiovascular drug development

The American College of Cardiology recently published findings in JACC: Basic to Translational Science that show the pace of innovation and investment in developing new cardiovascular therapeutics has decreased over the past 22 years.

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.
