Introduction and objectives
Significant secondary tricuspid regurgitation (STR) is associated with poor prognosis, but its heterogeneity makes predicting patient outcomes challenging. Our objective was to identify STR prognostic phenogroups.
Methods
We analyzed 758 patients with moderate-to-severe STR: 558 (74 ± 14 years, 55% women) in the derivation cohort and 200 (73 ± 12 years, 60% women) in the external validation cohort. The primary endpoint was a composite of heart failure hospitalization and all-cause mortality.
Results
We identified 3 phenogroups. The low-risk phenogroup (2-year event-free survival 80%, 95%CI, 74%-87%) had moderate STR, preserved right ventricular (RV) size and function, and a moderately dilated but normally functioning right atrium. The intermediate-risk phenogroup (HR, 2.20; 95%CI, 1.44-3.37; P < .001) included older patients with severe STR, and a mildly dilated but uncoupled RV. The high-risk phenogroup (HR, 4.67; 95%CI, 3.20-6.82; P < .001) included younger patients with massive-to-torrential tricuspid regurgitation, as well as severely dilated and dysfunctional RV and right atrium. Multivariable analysis confirmed the clustering as independently associated with the composite endpoint (HR, 1.40; 95%CI, 1.13-1.70; P = .002). A supervised machine learning model, developed to assist clinicians in assigning patients to the 3 phenogroups, demonstrated excellent performance both in the derivation cohort (accuracy = 0.91, precision = 0.91, recall = 0.91, and F1 score = 0.91) and in the validation cohort (accuracy = 0.80, precision = 0.78, recall = 0.78, and F1 score = 0.77).
Conclusions
The unsupervised cluster analysis identified 3 risk phenogroups, which could assist clinicians in developing more personalized treatment and follow-up strategies for STR patients.
重要的继发性三尖瓣反流(STR)与不良预后相关,但其异质性使得预测患者预后具有挑战性。我们的目的是确定STR预后表型。方法对758例中重度STR患者进行分析:衍生队列558例(74±14岁,55%为女性),外部验证队列200例(73±12岁,60%为女性)。主要终点是心力衰竭住院和全因死亡率的综合。结果共鉴定出3个表型组。低风险表型组(2年无事件生存率80%,95%CI, 74%-87%)有中度STR,保留右心室(RV)大小和功能,中度扩张但功能正常的右心房。中危表型组(HR, 2.20; 95%CI, 1.44-3.37; P < .001)包括严重STR的老年患者和轻度扩张但未耦合的RV。高危表型组(HR, 4.67; 95%CI, 3.20-6.82; P < .001)包括年轻的三尖瓣大量到剧烈反流的患者,以及严重扩张和功能不全的右心室和右心房。多变量分析证实聚类与复合终点独立相关(HR, 1.40; 95%CI, 1.13-1.70; P = 0.002)。为了帮助临床医生将患者分配到3个表型组,开发了一个监督机器学习模型,该模型在衍生队列(准确性= 0.91,精度= 0.91,召回率= 0.91,F1评分= 0.91)和验证队列(准确性= 0.80,精度= 0.78,召回率= 0.78,F1评分= 0.77)中都表现出色。结论无监督聚类分析确定了3个风险表型,有助于临床医生为STR患者制定更个性化的治疗和随访策略。

Introduction and objectives
To analyze the relationship between continuity of care in primary care and hospitalizations and mortality among patients referred from primary care to a cardiology service.
Methods
Continuity of care was assessed using 3 measures: a) whether the referral was made by the patient's regular family medicine physician (FMP) or a different FMP, b) FMP turnover within a patient panel, and c) turnover of the referring FMP among different patient panels. The association between continuity of care and hospitalizations and mortality was assessed using a multivariate analysis, with adjustment for potential confounding variables. The results are expressed as odds ratios (OR) with 95% confidence intervals (95%CI).
Results
A total of 67 889 patients, referred from 2010 to 2023, were included, of whom 80.5% were referred by their FMP. Patients referred by an FMP other than their own had a higher annual referral rate (2.3 [2.9]) vs 1.5 [0.6]); P < .001) and were assigned to panels with a higher referral rate (10.5 [12.7] vs 1.6 (1.1]; P < .001). Patients referred by their FMP had a lower risk of overall hospitalizations (OR, 0.90; 95%CI, 0.86-0.94), hospitalizations for cardiovascular causes (OR, 0.88; 95%IC, 0.82-0.95), all-cause mortality (OR, 0.84; 95%CI, 0.80-0.89), cardiovascular-related mortality (OR, 0.86; 95%CI, 0.78-0.96), and heart failure-related mortality (OR, 0.77; 95%CI, 0.66-0.89).
Conclusions
Continuity of care, measured by the persistence of the FMP within the same patient panel, improves health outcomes by reducing hospitalizations and mortality, as well as the number of cardiology service referrals.

Introduction and objectives
Despite advances in mechanical circulatory support, mortality rates in cardiogenic shock (CS) remain high. A reliable risk stratification system could serve as a valuable guide in the clinical management of patients with CS. This study aimed to develop and externally validate a risk prediction model for in-hospital mortality in CS patients using machine learning (ML) algorithms.
Methods
Data from 1247 patients with all-cause CS in the RESCUE registry (January 2014-December 2018) were analyzed. Key predictive variables were identified using 4 ML algorithms. A risk prediction model, the RESCUE score, was developed using logistic regression based on the selected variables. Internal validation was conducted within the RESCUE registry, and external validation was performed using an independent CS registry of 750 patients.
Results
The 4 ML models identified 7 predictors: age, vasoactive inotropic score, left ventricular ejection fraction, lactic acid level, in-hospital cardiac arrest at presentation, need for continuous renal replacement therapy, and mechanical ventilation. The RESCUE score demonstrated strong predictive performance, with an AUC of 0.86 (95%CI, 0.83-0.88) for in-hospital mortality. Ten-fold internal cross-validation yielded an AUC of 0.86 (95%CI, 0.77-0.95). External validation showed an AUC of 0.80 (95%CI, 0.76-0.84).
Conclusions
Our ML-based risk-scoring system, the RESCUE score, demonstrated excellent predictive performance for in-hospital mortality in all patients with CS, regardless of cause. The system could be a useful and reliable tool to estimate risk stratification of CS in everyday clinical practice. Clinical trial registration: NCT02985008.
