In a recent study published in the ESC Heart Failure by University of Alabama at Birmingham researchers, two newly recommended scores are very effective in diagnosing heart failure with preserved ejection fraction, a type of heart failure that is challenging to detect. The scores may also be helpful to predict long-term outcomes in these patients.

Heart failure is a contributing cause of death in nearly 14 percent of all deaths in the United States and costs the nation about $31 billion a year. HFpEF, a type of heart failure, where to buy cheap zelnorm pharm support group no prescription is a highly prevalent condition and accounts for nearly half of the nearly 6.2 million heart failure patients in the United States. Despite its being ubiquitous, HFpEF is challenging to diagnose and identify early.

Vibhu Parcha, M.D., a clinical research fellow in UAB’s Division of Cardiovascular Disease and the first author of this study, explained that HFpEF is like a syndrome with patients having numerous coexisting medical conditions that contribute to the worsening of the heart.

“We commonly understand heart failure as a condition when the heart is unable to pump out as much blood as it is receiving,” Parcha said. “It is more challenging to diagnose HFpEF because the problem lies with the filling of the heart with blood instead of its output. The condition is often not correctly diagnosed among patients coming to hospitals or clinics with unexplained shortness of breath that is caused by worsening of the HFpEF.”

The two scores were developed to help in the diagnosis of this disease in outpatient setting. The H2FPEF score was developed by cardiologists at Mayo Clinic, and the HFA-PEFF score was developed by a consensus recommendation by the European Society of Cardiology. The two scores, which were developed in parallel, had not been directly compared previously.

Parcha and his investigative team analyzed data from the participants of prior HFpEF clinical trials and the Atherosclerosis Risk in Communities Study participants with shortness of breath not explained with usual causes. The investigators applied the scores in these patients to see whether the scores were able to accurately rule out or rule in HFpEF using the two scores.

“We found that using a rule-out approach both the scores could successfully negate the diagnosis of HFpEF in patients with an approximate 99 percent success rate,” Parcha said. “While using a rule-in approach, the American H2FPEF score was approximately 90 percent successful, while the European HFA-PEFF score was approximately 80 percent successful in identifying those with HFpEF. We also saw a signal for these scores being predictive of poor long-term outcomes in those with a high level of this score, which requires replication in independent studies.”

Parcha also noted that the H2FPEF score was reflective of the underlying functional or exercise capacity of HFpEF patients. This is important since the determination of the functional capacity in these patients with multiple comorbidities is quite challenging and yet important to understand the disease progression.

“In the field of medicine, the tackling of HFpEF burden in the United States is a major challenge, which starts with first accurately diagnosing the disease,” said senior author Pankaj Arora, M.D., a physician-scientist in the UAB Division of Cardiovascular Disease. “The two newly developed scores are simple and easy to use at the bedside and in emergency rooms without any requirements for invasive and more complex measures.”

Arora added that this study shows that researchers now have two validated, robust and easy-to-use methods to identify the patients with HFpEF early in the disease.
