Young women with heart disease often experience atypical symptoms such as jaw pain, sweating, and shortness of breath. These individuals are twice as likely to die in the hospital compared to similarly aged men, highlighting the need for prompt medical attention and increased awareness of risk factors.
A randomized trial found that angioplasty significantly reduced long-term cardiac events compared to intensive drug therapy among heart attack survivors with silent ischemia. The study followed 201 patients for an average of 10.2 years, revealing a persistent benefit of PCI.
Two studies reveal that off-label and untested use of drug-coated stents is common in US practice, associated with higher ischemic complication rates and worse short-term outcomes. The studies found that approximately half of all use of drug-eluting stents occurs in off-label or untested settings.
A University of Kentucky study finds that doses higher than a baby aspirin may not prevent cardiovascular events and increase bleeding risk. The research suggests that using the minimum effective dose of 75-81 mg may be optimal for most patients.
A common genetic variation on chromosome 9p21 is linked to a substantial increase in risk for heart attack, with individuals carrying the variation having a 1.64-fold greater risk of suffering a heart attack. The study found that approximately 21 percent of individuals of European descent carry two copies of the genetic variation.

A new international study found that patients who received modern treatments after a heart attack or severe chest pain had significantly lower death rates, stroke risks, and heart failure. The study shows improved outcomes due to increased use of guideline-based treatments such as drugs, tests, and procedures.
The FDA has added 'black box' warnings to all prescription and over-the-counter pain relievers, despite evidence showing naproxen is safe. This decision ignores the risk differences between nonsteroidal anti-inflammatory drugs, with Voltaren carrying the highest risk of heart attack.
Researchers found HIV-infected patients had a higher incidence of heart attacks and major cardiovascular risk factors compared to noninfected patients. The study's findings indicate that HIV-infected individuals should be assessed for cardiovascular risks and that strategies to modify those risks are urgently needed.
A study published in JAMA found that ranolazine is safe but ineffective in reducing major cardiovascular events, such as death or heart attack, in patients with acute coronary syndromes. The medication showed a reduced risk of recurrent ischemia, but failed to improve overall cardiovascular outcomes.

This suggests that doctors are using alternative data sources, such as patient history and electrocardiogram results, to make treatment decisions.
A study of 119 Iowa hospitals found that rural hospitals do not have higher death rates for heart attack care, contrary to previous research. The study used a more sensitive analytic method to control for biases and found comparable patient outcomes.

A new analysis by Duke University Medical Center cardiologists found that taking low-dose aspirin daily reduces the risk of heart attack, stroke, and death among patients with stable cardiovascular disease. The study also showed an increased risk of bleeding, but the protective benefits of aspirin outweigh this side effect.
A study of over 44,000 patients found that blood transfusions were associated with a benefit in those with low hematocrit levels but harm in others. For patients with moderate hematocrit levels, transfusions showed no benefit or harm, suggesting providers may reconsider their decision-making process.
A large international clinical trial found that stable patients who received late angioplasty after a heart attack did not have better outcomes than those on medical therapy alone. The study suggests that routine late opening of the blocked artery is unnecessary and should be reserved for unstable patients.
A new study published in the New England Journal of Medicine found that patients who undergo angioplasty to open their totally blocked coronary arteries days after a heart attack do not reduce their risk of having another heart attack, going into heart failure, or dying. The study, which involved over 2,166 patients on five continents,...

Researchers found that TSA and SAHA decreased cholesterol deposits and prevented macrophages from forming foam cells inside arterial walls. These findings suggest the potential for these anti-inflammatory drugs to stabilize atherosclerotic plaque and reduce acute coronary events.
A study by Mayo Clinic researchers has found that people with psoriasis are more likely to develop heart disease, including heart attacks and heart failure. The study, which followed 622 adults with psoriasis and a control group of 622 people, found significant increases in cardiovascular events among those with psoriasis.
A recent study found that moderate drinking may be associated with a reduced risk of heart attack in healthy men. The research, conducted on 8,867 healthy men, suggests that even light drinkers have a lower risk than those who do not drink at all. Moderate drinking was linked to increased levels of HDL or 'good' cholesterol in the blood.
A new study published in Archives of Internal Medicine found that moderate drinking reduces men's heart attack risk. Among men with healthy lifestyles, those who consumed moderate amounts of alcohol had a 40-60 percent reduced risk of heart attack compared to non-drinkers and very light drinkers.
A study published in JAMA found that psoriasis patients are at a higher risk of heart attack, particularly those with severe psoriasis. Younger patients with severe psoriasis had the highest relative risk of heart attack, similar to other major cardiac risk factors.

The research also revealed that younger patients with severe psoriasis have a significantly increased relative risk compared to other major cardiac risk factors.
Researchers at Boston Children's Hospital developed a two-drug treatment that rescues heart function after a heart attack by promoting blood vessel growth and cell division. The study shows improved heart function and reduced scarring in rats treated with the combination of agents.

This finding offers hope for developing new drugs to modify Cox-2 production and prevent or lessen the severity of these conditions.
A team of researchers reviews existing research on LDL cholesterol and heart health, concluding that there is no valid evidence to support ultra-low LDL targets. They suggest focusing on statin therapy for high-risk patients regardless of their cholesterol levels.
