A new paper published in Circulation outlines a new test for diagnosing&nbsp;<a href="https://proddocwire.wpengine.com/cardiology/swedish-adoption-study-heart-failure-heritability/">heart failure</a>&nbsp;with&nbsp;<a href="https://proddocwire.wpengine.com/cardiology/primary-and-secondary-diastolic-dysfunction-in-heart-failure-with-preserved-ejection-fraction/">preserved ejection fraction</a>&nbsp;(HFpEF) in&nbsp;euvolemic&nbsp;patients with dyspnea.&nbsp;&nbsp;The authors retrospectively looked at 414 consecutive patients with unexplained dyspnea and obtained diagnoses of HFpEF (case) and noncardiac dyspnea (control) using invasive hemodynamic exercise testing. They then used logistic regression to evaluate how well clinical findings could discriminate cases from controls and developed a scoring system using a separate test cohort (n=100 consecutive patients). The weighted score (H2FPEF) included 6 predictive variables: obesity, atrial fibrillation, age &gt;60 years, treatment&nbsp;with &ge;2 antihypertensive medications, echocardiographic E/e&rsquo; ratio &gt;9, and echocardiographic pulmonary artery systolic pressure &gt;35 mm&thinsp;Hg)&nbsp;and ranged from 0 to 9.&nbsp;According to their analysis, each 1-unit score increase was associated with a doubling in the odds of&nbsp;HFpEF&nbsp;(OR=1.98; 95% CI, 1.74 to 2.30; P&lt;0.0001) with an AUC of 0.841 (P&lt;0.0001). They also reported maintained performance in the independent&nbsp;cohort&nbsp;(AUC=0.886; P&lt;0.0001).&nbsp;The&nbsp;H2FPEF&nbsp;score was found to be superior to the current expert consensus-derived algorithm (increase in AUC=0.169; 95% CI, 0.120 to 0.217; P&lt;0.0001.&nbsp;&ldquo;The H2FPEF score, which relies on simple clinical characteristics and echocardiography, enables discrimination of&nbsp;HFpEF&nbsp;from noncardiac causes of dyspnea and can assist in determination of the need for further diagnostic testing in the evaluation of patients with unexplained exertional dyspnea,&rdquo; the&nbsp;authors&nbsp; wrote.&nbsp;<blockquote class="twitter-tweet" data-width="500" data-dnt="true">

Reasonable on several accounts but still weak on defining mathematics. HFpEF implies EF as a marker of Systole. HFpEF is therefore the mirror of EF calculation for Diastole. Application of volumetrics to both equations may expand utility in separating systolic vs diastolic HF. <a href="https://t.co/JpxhyePkfq">https://t.co/JpxhyePkfq</a>
