Hemodynamic Patterns and Left Ventricular Function Recovery in Peripartum Cardiomyopathy: A Comprehensive Echocardiographic Analysis.
Article in JACC. Asia, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe influence of hemodynamic changes at presentation on the recovery of left ventricular (LV) function in peripartum cardiomyopathy (PPCM) patients remains uncertain.
objectivesThis study aims to identify hemodynamic patterns in individuals with PPCM.
methodsThis study included women with PPCM from 2 databases in Israel and Indonesia. Conventional echocardiography, 2-dimensional strain, myocardial work, and noninvasive pressure-volume loop analysis were performed with subsequent data clustering.
resultsAmong 89 women (median age 32 years, IQR: 8.7 years; LV ejection fraction [EF] 36.0%, IQR: 11.5%), 63 (70.8%) experienced LV function recovery (LVEF ≥50%) during 6 months of follow-up. Gestation hypertension/pre-eclampsia and LVEF >35% and LVDD ≤55 mm at presentation were associated with LV recovery. Significant hemodynamic variability was observed, indicating a nonuniform PPCM pattern. Cluster analysis of 43 patients identified 3 hemodynamic subtypes. In cluster 1, patients exhibited the lowest rate of LV recovery (12.5%), profound contractility impairment, severe LV remodeling, and reduced cardiac output (CO). Cluster 2 showed a high LV recovery rate of 78.6%, prevalent in Southeast Asian patients with gestational hypertension. These patients displayed decreased CO and extremely elevated afterload. Load-dependent contractility indexes, like LVEF and global longitudinal strain, were markedly reduced, while load-independent end-systolic elastance remained unaffected, indicating afterload-dependent contractility impairment. All patients in cluster 3 recovered LVEF, presenting mildly reduced contractility indexes, mild ventricular dilatation, slightly increased afterload, and preserved CO.
conclusionsPPCM exhibits heterogeneous hemodynamic patterns, with 3 distinct phenotypes displaying varying rates of LV recovery. Understanding the heterogeneity in PPCM hemodynamic phenotypes can guide optimal treatment.
