Abstract

Introduction:

Peripartum cardiomyopathy (PPCM) is a pregnancy related cardiomyopathy with a high potential for recovery. One of the contemporary predictors studied in cardiomyopathy is right ventricular (RV) function during initial presentation.

Purpose:

This study aimed to determine the role of RV systolic function based on the various RV function parameters by two-dimensional transthoracic echocardiography (2DE) to predict PPCM recovery within 6 months of follow-up and identify the most accurate parameter among them.

Patients And Methods:

This was a prospective cohort study that include all patients registered in the "Long Term Registry on Patients with Peripartum Cardiomyopathy" at Dr. Hasan Sadikin General Hospital Indonesia during period of September 2014 until December 2022. Right ventricular systolic dysfunction was defined as abnormal value in one or more parameter(s), including tricuspid annular plane systolic excursion (TAPSE), fractional area change (FAC), S', right ventricular free wall longitudinal strain (RVFWLS) and right ventricular global longitudinal strain (RVGLS). Left ventricular ejection fraction was measured on initial examination and after 6-month follow up to define recovery.

Results:

A total of 95 patients were included in this study. There were 33 patients (34.7%) with reduced initial RV systolic function. Sixty-four patients (67.4%) recovered within 6 months follow up. The recovery rate of patients with initial RV systolic dysfunction is lower than patients with normal RV systolic function (51.5% vs 75.8%, p = 0.016). This study showed that initial RV systolic dysfunction can predict poor LV function recovery in PPCM patients (OR 0.340; 95% CI:0.120-0.959; p = 0.041). Among all RV function parameters, only FAC (OR 1.076; 95% CI:1.003-1.154; p = 0.040)) and RVGLS (OR 0.768; 95% CI: 0.595-0.991; p = 0.042) emerged as independent predictors of PPCM recovery.

Conclusion:

Right ventricular function in terms of FAC and/or RVGLS at initial diagnosis can be used as a predictor for PPCM recovery at 6 months follow-up.

Cardiomyopathy I: Introduction and Classification

Cardiomyopathy I: Introduction and Classification

Cardiomyopathy, or CMP, is a group of diseases affecting the myocardial structure, impairing its ability to pump blood effectively. This condition can lead to arrhythmias, heart failure, or sudden cardiac death.Cardiomyopathies are classified into primary and secondary categories:Primary Cardiomyopathy refers to conditions involving only the heart muscle that are often idiopathic (of unknown cause) or genetic. They primarily affect the myocardium without the involvement of other systemic...

Cardiomyopathy II: Dilated Cardiomyopathy

Cardiomyopathy II: Dilated Cardiomyopathy

Dilated cardiomyopathy, or DCM, is a progressive myocardial disorder characterized by ventricular chamber dilation and contractile dysfunction.EtiologyVarious factors can cause DCM, including hypertension and heavy alcohol intake, which contribute to the weakening and enlargement of the heart muscle. Viral infections, such as Coxsackievirus B, adenoviruses, and influenza, can lead to DCM by causing inflammation and damage to heart tissue. Certain chemotherapeutic agents, including daunorubicin,...

Cardiomyopathy III: Hypertrophic Cardiomyopathy

Cardiomyopathy III: Hypertrophic Cardiomyopathy

Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...

Cardiomyopathy IV: Restrictive Cardiomyopathy

Restrictive cardiomyopathy (RCM) is a rare heart muscle disease characterized by impaired ventricular filling due to stiffened ventricular walls, leading to significant diastolic dysfunction.EtiologyRestrictive cardiomyopathy can arise from both inherited and acquired diseases, many of which are systemic. It is categorized into four main types: infiltrative, storage, non-infiltrative, and endomyocardial diseases.Infiltrative diseases, such as amyloidosis, lead to RCM by depositing amyloid...

Cardiomyopathy V: Interprofessional Care

Managing cardiomyopathy involves addressing underlying or precipitating causes, treating heart failure with medications, and implementing dietary changes and a balanced exercise and rest regimen.Lifestyle ModificationsCardiomyopathy patients should adopt a low-sodium diet to reduce fluid retention and manage heart failure. A personalized exercise and rest plan helps maintain physical fitness without overstraining the heart. Avoiding alcohol and tobacco is essential to prevent further damage to...

Cardiomyopathy VII: Pre and Post Operative Nursing Management

Patients with hypertrophic cardiomyopathy (HCM) and left ventricular outflow tract (LVOT) obstruction who remain symptomatic despite optimal medical therapy may undergo a septal myectomy (Morrow procedure). This procedure involves excising a portion of the hypertrophied septum below the aortic valve using a heart-lung machine to improve blood flow through the LVOT. Effective preoperative and postoperative nursing management ensures successful patient outcomes, minimizes complications, and...
