A study published in The Lancet suggests that routine heart scans for patients referred to cardiac clinics with chest pain could reduce heart attack rates. The SCOT-HEART trial found that around a quarter of patients had their diagnoses reclassified after receiving the scan, prompting new treatments in many cases.
A large study has found that routine blood clot removal during heart attack treatment does not benefit patients and may increase the risk of stroke. The TOTAL trial involved over 10,700 patients and showed no differences in cardiovascular outcomes between those who received clot removal and those who did not.
The study found that Bendavia did not prevent irreversible injury to the heart but showed a trend towards improved heart pumping function. The drug is well-tolerated but lacks significant benefits in reducing scarring from angioplasty after a heart attack.
The study found that adding ticagrelor to aspirin therapy after a heart attack significantly reduced the rate of subsequent death from cardiovascular causes, with benefits appearing for nearly three years. The trial recruited 21,162 patients and showed a 15% reduction in cardiovascular death with both ticagrelor doses.

Genetic analysis assesses heart attack risk independently of traditional factors, identifying those at higher baseline risk who reap greater benefits from therapy. The study's findings have implications for precision medici...
A recent meta-analysis of 36 studies found that moderate coffee consumption is associated with a decreased risk of heart disease. Participants who consumed 3-5 cups of coffee per day had the lowest risk of clogged arteries and heart attacks.

A new study found that most heart attack patients do not receive sexual counseling from their healthcare provider, with only 12% of women and 19% of men reporting such advice. The researchers recommend that healthcare providers raise the issue of resuming sexual activity with their patients, as it is an important aspect of overall health.
Researchers at Imperial College London discovered a possible way to identify which patients should avoid using COX-2 inhibitors, a type of non-steroidal anti-inflammatory drug (NSAID), due to increased heart attack risk. The study found that COX-2 inhibitors raise levels of ADMA, an independent risk factor for cardiovascular disease.

A new study published in JAMA found that hospitalized patients with STEMI heart attacks are more likely to die than those who had the same type of heart attack outside the hospital. The study analyzed data from over 62,000 patients and found that these patients were older, female, and less likely to receive routine treatments for STEMI.
Patients who develop heart attacks in hospitals for non-acute conditions have a 3.5-fold higher mortality rate compared to those with outpatient-onset STEMI. Inpatient-onset STEMI patients are also less likely to be discharged home and undergo necessary treatments, leading to longer hospital stays and higher costs.
Research at Mayo Clinic reveals that patients with active asthma are at a twofold risk of having a heart attack. Patients with inactive asthma were not found to be at an increased risk, highlighting the need for better control of asthma symptoms and medication use.
A recent study by Duke University researchers found that over half of STEMI heart attack patients had one or both of their other arteries obstructed, leading to worse outcomes. The study suggests that opening all blocked arteries may become a standard procedure.

The study suggests that these survivors should be screened for functional disability long after discharge from the hospital.
A new study published in PLOS ONE suggests that a dose of iodide can significantly reduce the damage caused by reperfusion injury after a heart attack. The study found that intravenous infusions of sodium iodide reduced myocardial infarction damage by up to 75 percent in mice, and oral iodide showed similar protective effects.
A study of nearly 38,000 patients found that those diagnosed with nonobstructive coronary artery disease (CAD) had a significantly increased risk of heart attack or death one year after diagnosis. Patients with nonobstructive CAD had an associated risk of MI that was 2-to 4.5-fold greater than among those with no apparent CAD.
A recent study highlights the dangers of women delaying medical attention for heart symptoms, citing a higher likelihood of severe or advanced stage treatment options being limited. Women often attribute symptoms to other possibilities and exhibit an optimistic bias, waiting longer to seek care than men.
A clinical study found that high levels of TMAO, a chemical byproduct of intestinal bacteria digestion, are linked to an increased risk of heart failure and poor long-term prognosis. Patients with low TMAO levels had a lower mortality rate despite advanced heart failure symptoms.
A new study by researchers at Intermountain Medical Center Heart Institute suggests that lifestyle choices, not just genetics, may contribute to the risk of heart attack. The study found that severe coronary artery disease can be inherited, but the presence of heart attacks in people with less severe disease was not clustered in families.
According to research presented at Acute Cardiovascular Care 2014, nearly one quarter of patients in the study were depressed and nearly a quarter had received treatment for depression. Women were more likely to develop anxiety and depression after a heart attack compared to men, with current smokers also showing higher levels of anxiety.
Researchers at UNC School of Medicine have discovered a new way to generate more blood vessels following a heart attack by turning fibroblasts into endothelial cells. Increasing the level of p53 in scar-forming cells significantly reduces scarring and improves heart function after heart attack.
Researchers at UCLA have discovered that fibroblasts can transform into endothelial cells, which form blood vessels. This finding suggests a potential new strategy for improving heart repair after a heart attack.
Researchers have found that post-heart-attack arrhythmias are triggered by a power grid-like failure inside cardiac cells, disrupting mitochondria and causing chaotic cell-to-cell signaling. This disruption can lead to life-threatening arrhythmias like fibrillation, but pretreatment with certain medications may help prevent them.
