Heart Failure

Despite positive results seen from the use of chloroquine and hydroxychloroquine in some patients hospitalized with coronavirus disease 2019 (COVID-19), concern is mounting about how these drugs affect patients’ cardiovascular health, specifically the heart.

The chemical symbol for iron is Fe, which stems from the Latin word for iron, Ferrum. Therefore, it is easy to see the connection on how ferritin is the protein responsible for iron storage and release in the body and transferrin is the protein responsible for transporting that iron.

Does patient representation in trials of acute coronary syndrome (ACS) correlate with epidemiologic studies of patients with the condition? According to recent results published in JAMA Cardiology, older patients, women, and black patients continue to be underrepresented in ACS trials.

Almost 70% of the world’s population could be living in urban areas, being continuously exposed to air pollution, by 2050, while cases of dementia are expected to triple. Recent study results highlight the link between cardiovascular disease and dementia, as mediated by long-term exposure to air pollution.

Dapagliflozin is currently indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes (T2D). In the United States, it is also approved to reduce the risk of hospitalization for heart failure in patients with T2D and established cardiovascular (CV) disease or multiple CV risk factors.

Pregnancy complications that include preeclampsia, gestational hypertension, pre-term birth, and low birthweight serve as possible indicators for greater risk of heart failure in the long term, as indicated by change in global longitudinal strain on echocardiogram.

Evidence is considered lacking on the association between mortality and patients who have both cardiac injury and coronavirus disease 2019 (COVID-19). Is the rate of death higher among these patients compared with patients without cardiac disease who have COVID-19?

Are coding changes responsible for declines in the 30-day mortality rate for hospital admissions among veterans utilizing Veterans Health Administration medical centers? Which model is more accurate at predicting this measure: a claims-based model or a clinical factor–based model?

By 2030, heart failure—which tops the list of reasons for hospitalization among individuals older than 65 years—could tax the healthcare system $69.8 billion each year. Study results show the success of palliative care at reducing both healthcare costs and hospitalization.

Patients with cardiovascular disease are especially vulnerable to respiratory infections, although uncertainty remains on just what damage COVID-19 can cause in these patients. The flu season is also in full swing, with an estimated 440,000 individuals hospitalized so far in the United States alone, according to the CDC.

Eighty percent of annual costs for heart failure come from hospitalization for the condition, which more than 23 million persons suffer from worldwide, 6.2 million (27%) in the United States alone. These costs are estimated to increase almost 58% between 2012 and 2030, from $30.7 billion to $53 billion.

Barriers to better treatment start with the basic definitions of heart failure. Classifications in use for decades, such as the New York Heart Association system or the left ventricle ejection fraction measure, need an overhaul, and the field should take a precision medicine approach that brings analytics and biomarkers to the cause.

Updated results from the EASEL study show that lower risks of cardiovascular (CV) events, CV death, and CV mortality accompany initiation of canagliflozin, a sodium glucose cotransporter 2 inhibitor, in patients with type 2 diabetes (T2D) and high CV risk compared with use of other drugs.

Circulation, a peer-reviewed journal of the American Heart Association, just released its fourth annual Go Red for Women issue, in which researchers from the Smidt Heart Institute at Cedars-Sinai note the stark disparities in how heart disease manifests in women and men. For women, sudden cardiac death is often the first sign they even have heart disease.

Competing trials are under way that may show that the benefits of SGLT2 inhibitors in heart failure are a class effect.

There are more than 36 million smokers in the United States today, and most (70%) admit they want to quit. Individuals who decide to quit see a smaller risk of heart disease within 1 to 2 years, along with reduced risks of stroke and peripheral vascular disease. However, annual deaths from smoking still exceed 480,000 in the United States, where over 16 million live with smoking-related diseases that include infertility, lung cancer, and chronic obstructive pulmonary disease.

GUARD-AF is an example of the commitment of the BMS, Pfizer Alliance in trying to further the standard of care in patients with atrial fibrillation, said Roland Chen, MD, MS, vice president and head of clinical development for innovative medicines at Bristol-Myers Squibb.

In 2017, heart failure contributed to 1 in 8 deaths. This inability of the heart to function at its optimal level led to an estimated $30.7 billion in annual healthcare costs in 2012, including healthcare services, medicines, and missed work.

The most detailed look ever at data for rosiglitazone, the diabetes drug marketed by GlaxoSmithKline (GSK) as Avandia, shows the one-time blockbuster significantly raises the overall risk of heart problems or cardiovascular death, calling attention to the need for more transparency in data collection.

Improving recognition of the link between heart failure and diabetes can promote preventive care for at-risk patients, said Javed Butler, MD, MPH, MBA, professor of physiology and chairman for the Department of Medicine at the University of Mississippi.

The drug-shock strategy was more effective for patients experiencing atrial fibrillation for the first time and for patients younger than 70 years, the researchers said.

Heart failure (HF) taxes the American healthcare system by a total of $39.2 billion to $60 billion each year. This amount is expected to increase up to 20% by 2030 and total $70 billion. Worldwide, HF has been diagnosed in 26 million individuals, and this number is rising.

The authors write that the drug's apparent cardioprotective effects in the angiotensin II stressed mice—the decreased fibrosis, reduced inflammation and oxidative stress—all merit further study.

Hypertrophic cardiomyopathy is an abnormal thickening of the heart muscle, with causes that include genetic mutations and myofiber disarray (an abnormal heart muscle cell arrangement). Individuals who have this condition are prone to obesity (body mass index, 25 to

Diabetes Can Break Your Heart is an important initiative that highlights the vital need for heightened education on the link between diabetes and heart failure, especially with American Heart Month looming, said Javed Butler, MD, MPH, MBA, professor of physiology and chairman for the Department of Medicine at the University of Mississippi.
