Easy Access: Studies to Note

Many studies have been published discussing the heart, access to health care, and advances in drug prescribing. Some of the more relevant deal with the early stages of diagnosis:

A cardiac study shows the potential benefit of genetic testing in choosing blood thinners

Some patients go through extensive tests to get a diagnosis. So what else is a blood test in the long run?

A new blood test could help patients and their doctors reduce the risk of the serious harmful effects that can occur after frequent treatment for heart conditions. Patients undergoing balloon angioplasty to install stents in the heart must then take blood thinners (anticoagulants) to prevent blood clots. However, clopidogrel, the blood thinner traditionally prescribed to most patients, does not work in almost a third of them. As a result, these patients are at greater risk of heart attack or stroke in the years following treatment. Using genetic testing on a blood sample, doctors can reduce the risk of the drug not working by 34% by knowing who is not responding to clopidogrel

If patients test positive for the genetic variant that is keeping clopidogrel from working, their doctors may prescribe a different blood thinner that may work better. The study was expanded to learn more about which prescriptions are best for individual patients.

More than half of those who suffered from “sudden” cardiac arrest had previously contacted health care providers

Cardiac arrests are often viewed as a sudden, immediate event. However, a new study found that sudden cardiac arrest victims in the past two weeks may have some warning signs.

Research by the European Society of Cardiology shows that 58% of people who experienced "sudden" cardiac arrest had seen a doctor in the previous weeks. In a study carried out from 2001 to 2014, the researchers came to the conclusion that many patients felt unwell 2 weeks before the cardiac arrest.

Counting minutes when someone's heart stops. This revelation could help doctors and patients recognize more warning signs and be better prepared for the "sudden" events. Further research is needed to determine the average reasons for patients contacting their GP within a few weeks of a sudden cardiac arrest.

Acute cardiovascular events, which are common in adults with influenza

It seems we can't get away from talking about respiratory diseases these days. Influenza, commonly known as the flu, hospitalizes between 140,000 and 810,000 people in the United States each year. Studies are now showing, just like with COVID-19, that some of these patients have cardiovascular side effects in the hospital.

The researchers used data from the U.S. Influenza Hospitalization Surveillance Network over the past two flu seasons to determine that nearly 12% of hospitalized patients with influenza had some form of acute cardiovascular event. These patients were most likely to have heart failure and acute ischemic heart disease, also known as coronary artery disease or coronary artery disease. The results of the study suggest that vaccination is an important step in preventing these cardiovascular events in patients who fall into the risk factor categories.

Study shows socioeconomic status related to heart failure mortality in the US

Everyone has a heart, but taking care of their health can be more of a challenge for some than for others.

A study published in early August found that the lack of a diagnosis of heart disease in US states with high poverty rates could be due to wealth gaps. University clinic researchers found that there may be a link with policies on wealth, socio-economic status and access to health care.
Using data on deaths from heart failure in 3,048 counties between 1999 and 2018, the researchers highlighted the role that healthcare disparities play for underserved communities. According to one of the co-authors, the trend in mortality from heart failure in socio-economic areas has been sustained for two decades. The researchers hope that these and similar studies can offer solutions to better serve communities whose health care is less than that of others.
