Researchers at UT Southwestern have found that SR-B1 and DOCK4 proteins ferry LDL particles into and across endothelial cells, driving the development of atherosclerosis. Deleting these proteins from endothelial cells reduces LDL entry and atherosclerotic plaque formation.
A study from Yale University finds that low mobility is a significant predictor of hospital readmission in older heart attack patients. Patients who took more than 25 seconds on the Timed Up and Go test were nearly twice as likely to be readmitted after a heart attack.
A new prediction tool uses functional impairments and traditional factors to identify patients over 75 who may require repeat hospitalization. Impaired mobility, measured by the Timed Up and Go test, is the only functional impairment associated with 30-day readmission.
A new study found that percutaneous coronary intervention (PCI) significantly reduced overall mortality in older heart attack patients. The procedure saved lives for 49 young-olds, 53 middle-olds, and 54 old-olds, with a 53% reduction in death among those 75-79 years old.
A Northwestern University and UC San Diego team has created a novel way to deliver a bioactivated, biodegradable substance through a noninvasive catheter without clogging. The approach uses self-assembling peptides that turn the body's inflammatory response into a signal to heal rather than a means of scarring.
Researchers have identified two microRNA family members that can provide both immediate and long-term protection against heart damage. The therapy targets the miR-19a/b microRNAs, which regulate proliferation of cardiomyocytes and reduce inflammation, leading to improved heart function.
A study published in the European Journal of Preventive Cardiology found that people who skip breakfast and eat dinner near bedtime have a four to five times higher likelihood of death, another heart attack, or angina within 30 days after hospital discharge for heart attack. Late-night dinner eating was also associated with poorer outc...
Researchers have developed a water-based hydrogel material that can be placed directly on the heart to prevent stretching of the heart muscle, a common problem after a heart attack. The patch outperformed existing patches and showed promising results in reducing post-heart attack damage.
Patients with acute coronary syndromes can return to work in two to three months, but one in four quit after a year. Psychological factors like lack of confidence, depression, and anxiety are significant predictors of failure. Attending cardiac rehabilitation and gradual reintegration into the workplace can help patients succeed.
Researchers found that older heart attack patients were less likely to receive timely percutaneous coronary intervention (PCI) to open blocked heart arteries, resulting in more complications and poorer outcomes. Despite longer hospital stays, older patients had lower total charges due to reduced use of costly interventions like PCI.
Despite improvements in heart attack and heart disease care for older women, black women continue to face significant racial disparities in treatment. Postmenopausal black women were 50% less likely and Hispanic women 16% less likely to receive treatment when arriving at the hospital with symptoms compared to white women.
A genetic study of over 160,000 adults in China found that moderate drinking has no protective effects against stroke and may even increase the risk. Blood pressure also rises with increased alcohol consumption.

A new study shows that a 4 gram dose of icosapent ethyl significantly reduces the occurrence of ischemic events, including heart attacks, strokes, and related deaths. The drug also prevents subsequent cardiovascular events and may be a cost-effective way to prevent CV complications in patients with elevated triglycerides.
Researchers found that ticagrelor has comparable efficacy to clopidogrel in patients treated with clot busters for a heart attack. The trial also showed that ticagrelor is safe for use in this patient population, with low rates of major bleeding.
Researchers found that systematic depression screening after a heart attack did not impact patients' quality of life. Depression was identified in about 7% of screened patients, and interventions such as medication, phone-based psychotherapy sessions, or a combination both were shown to be effective in reducing depressive symptoms.
A Yale study of over four million Medicare patients found that hospitalizations for heart attacks have declined by 38% since the 1990s, while the 30-day mortality rate has dropped to an all-time low of 12%. These gains are attributed to national efforts to prevent heart attacks and improve care.
A study of over 27,000 heart attack patients found an increase in heat-induced heart attacks in recent years, particularly among individuals with diabetes or hyperlipidaemia. Climate change is suspected to be a contributing factor, but the exact mechanism behind these deaths remains unclear.
Researchers found that lower blood pressure is associated with increased risk of death in adults over 80, and those who've had a heart attack or stroke. This study's results suggest adjusting antihypertensive treatment based on individual needs, moving away from blanket approaches.
A large study of nearly 30 million hospital records shows that people who got a flu shot while hospitalized had a 10 percent lower risk of having a heart attack compared to those who didn't get vaccinated. The findings suggest that getting a flu vaccine can reduce the risk of major cardiovascular problems.

A new study published in the International Journal of Cardiology confirms that diets rich in palmitic and stearic acid, found in meats, increase cardiovascular risk. In contrast, eating fewer long-chain saturated fats and consuming plant-based proteins lowers the risk of myocardial infarction.
A new study published in JAMA found that frequent aspirin use can lead to a 50% increase in major bleeding episodes. While aspirin reduces cardiovascular event risks, it increases the risk of major bleeding, making its use for initial prevention uncertain.
A study of 325,000 hospitalized heart attack patients found that Medicaid expansion reduced uninsurance rates but did not improve quality of care or outcomes for low-income adults. The lack of insurance was still associated with worse care and outcomes in both expansion and non-expansion states.
A new study published in the European Heart Journal found that individuals with higher fitness levels have a lower risk of heart attacks and angina pectoris over nine years. Even among seemingly healthy individuals, those with optimal fitness have only half as high a risk as those with poor fitness.
A new study has found a genetic factor on chromosome 6 that increases the risk of spontaneous coronary artery dissection (SCAD), a rare and atypical form of heart attack primarily affecting young to middle-aged women. The genetic variant, known as rs9349379, is also associated with a small protective effect from classic heart attacks.
An observational study found that HRRP implementation was associated with increased 30-day postdischarge mortality for heart failure and pneumonia patients. However, no association was seen for patients hospitalized for heart attack.

The risk was highest for patients with lung and colorectal cancers and those diagnosed with stage 3 or 4 disease, peaking in the month before diagnosis.
A Swedish study found that the risk of heart attack peaks at around 10 pm on Christmas Eve, especially for older and sicker individuals due to heightened emotional stress. This risk is also higher during New Year's and Midsummer holidays, as well as Monday mornings.
Scientists at the Peter Munk Cardiac Centre have discovered that macrophage cells play a crucial role in helping the heart repair and regenerate following a heart attack. The study found that these cells can act in a neo-natal-like state, aiding in tissue growth and development.
A comprehensive statistical modeling study found that statins are recommended far too often, with the benefits outweighing the harms only in people with a high risk of cardiovascular disease. The researchers recommend discussing individual risk and side effects with doctors before taking statins as a preventive measure.
Researchers at the Hubrecht Institute found that adult hearts do not have stem cells that can regenerate lost heart muscle after a heart attack. Instead, connective tissue cells produce scar tissue to replace the lost cardiac muscle, which helps maintain heart integrity.
