U-M cardiologists reveal impact from shortage of radioactive elements used in cardiac stress testing

U-M cardiologists reveal impact from shortage of radioactive elements used in cardiac stress testing

Nearly 15 million times a year, Americans with heart trouble climb onto a treadmill to take a stress test that can reveal blockages in their heart's blood vessels. It's a major factor in deciding what doctors should do next for them. [More]
Simple diagnostic algorithm to assess pulmonary embolism risk can help reduce rate of CTPA imaging

Simple diagnostic algorithm to assess pulmonary embolism risk can help reduce rate of CTPA imaging

Patients with suspected pulmonary embolism (PE) often undergo computed tomography pulmonary angiography (CTPA) to confirm or exclude the diagnosis. [More]
New study suggests major change in treatment of significant number of ACS patients

New study suggests major change in treatment of significant number of ACS patients

More than one quarter of heart attack patients who are normally treated with stents to re-open their blocked arteries might be able to forgo this procedure and receive anti-thrombotic medications only, according to results of a pilot study. [More]
BBK II trial compares two commonly used stenting techniques for coronary bifurcation

BBK II trial compares two commonly used stenting techniques for coronary bifurcation

Coronary bifurcations - a type of coronary artery narrowing - are best treated with a technique known as culotte stenting, as opposed to T-and-protrusion (TAP) stenting, when there is need for a side-branch stent according to results of the BBK II (Bifurcations Bad Krozingen) trial. [More]
CE-MARC 2 trial finds way to reduce rates of unnecessary invasive angiography

CE-MARC 2 trial finds way to reduce rates of unnecessary invasive angiography

Initial investigation of patients with suspected coronary heart disease (CHD) using functional imaging - rather than guideline-directed care - resulted in significantly less unnecessary angiography, according to results of the CE-MARC 2 trial. [More]
Lipoprotein apheresis may have new role in patients with refractory angina

Lipoprotein apheresis may have new role in patients with refractory angina

Initial investigation of patients with suspected coronary heart disease (CHD) using functional imaging - rather than guideline-directed care - resulted in significantly less unnecessary angiography, according to results of the CE-MARC 2 trial. [More]
PACIFIC study may offer guidance to choose from number of non-invasive coronary artery imaging

PACIFIC study may offer guidance to choose from number of non-invasive coronary artery imaging

For patients presenting for the first time with suspected coronary artery disease (CAD) clinicians have had a number of non-invasive diagnostic tests to choose from, but little evidence for which is best. [More]
Invasive imaging technique can help achieve better outcomes in patients undergoing PCI

Invasive imaging technique can help achieve better outcomes in patients undergoing PCI

An invasive imaging technique called optical coherence tomography (OCT) can visualize the coronary arteries in patients undergoing percutaneous coronary intervention (PCI) and lead to better outcomes compared to standard angiography-guided PCI, according to new findings reported here. [More]
HIJ-PROPER trial: Intensive cholesterol-lowering regimen in ACS patients shows no better outcomes

HIJ-PROPER trial: Intensive cholesterol-lowering regimen in ACS patients shows no better outcomes

Survival and other cardiovascular outcomes were not significantly reduced with intensive treatment using a second-line cholesterol-lowering medication on top of a standard statin, compared to statin treatment alone in patients with acute coronary syndrome (ACS) and dyslipidemia, investigators reported here.

Study shows link between inflammatory biomarkers and prevalence of CAD in HIV-infected men

Study shows link between inflammatory biomarkers and prevalence of CAD in HIV-infected men

A cardiac imaging study led by Hossein Bahrami, MD, PhD, assistant professor of cardiovascular medicine at the Keck School of Medicine of the University of Southern California, along with investigators from Johns Hopkins University and five other institutions, showed a correlation between higher inflammatory biomarkers and an increased prevalence of coronary artery disease (CAD) in men infected with human immunodeficiency virus (HIV).

Hidden dental root tip infections may increase risk of coronary artery disease

Hidden dental root tip infections may increase risk of coronary artery disease

According to a study carried out at the University of Helsinki, an infection of the root tip of a tooth increases the risk of coronary artery disease, even if the infection is symptomless. [More]
Cardiac troponin test refines ACS rule-out process

Cardiac troponin test refines ACS rule-out process

Testing high-sensitivity cardiac troponin T levels in patients with acute coronary syndromes reduces their need for cardiac stress testing and speeds their discharge from the emergency department, report researchers. [More]
Athens QRS score flags false-negative exercise stress tests

Athens QRS score flags false-negative exercise stress tests

Patients with a low Athens QRS score are highly likely to have coronary artery disease even if they have a normal exercise stress test, say researchers. [More]
Right ventricular echocardiography predicts targeted therapy outcome in PAH

Right ventricular echocardiography predicts targeted therapy outcome in PAH

Echocardiography re-assessment of right ventricular function after targeted therapy is sufficient to predict subsequent prognosis in patients with pulmonary arterial hypertension, say researchers. [More]

Artificial intelligence could refine CAD prognosis

A study shows that machine learning can predict mortality in patients with coronary artery disease with greater accuracy than models based on coronary computed tomographic angiography or clinical variables. [More]
CMR could offer complete imaging solution before pulmonary vein isolation

CMR could offer complete imaging solution before pulmonary vein isolation

Cardiac magnetic resonance can potentially be used to detect thrombi at the same time as being used for pulmonary venous anatomy mapping, say researchers [More]
Neutral atherosclerosis trial highlights effectiveness of optimal medical therapy

Neutral atherosclerosis trial highlights effectiveness of optimal medical therapy

Salsalate has no greater effect than placebo on the progression of coronary artery plaque, show the findings of the randomised TINSAL-CVD trial. [More]
CMR 'may be preferable' to SPECT for CHD prognosis

CMR 'may be preferable' to SPECT for CHD prognosis

Long-term follow-up of the CE-MARC study suggests that cardiovascular magnetic resonance could be a better predictor of cardiovascular events than single-photon emission computed tomography in patients with coronary heart disease. [More]
Important signs, symptoms of stroke that everyone should know

Important signs, symptoms of stroke that everyone should know

Almost 795,000 Americans suffer from stroke each year, 130,000 which are fatal, making stroke the fifth leading cause of death in the United States. [More]
Study shows women undergoing TAVR have longer-term survival rate compared to men

Study shows women undergoing TAVR have longer-term survival rate compared to men

Data from one of the largest national registries of transcatheter aortic valve replacement (TAVR) patients shows that although women are more likely to experience vascular complications in the hospital, their one-year survival rate is more favorable than men. [More]
