Disparities in Cardiac Rehabilitation Among Individuals from Racial and Ethnic Groups and Rural Communities-A Systematic Review.

PURPOSE: Despite the well-described benefits of cardiac rehabilitation (CR) on long-term health outcomes, CR is a resource that is underutilized by a significant proportion of patients that suffer from cardiovascular diseases. The main purpose of this study was to examine disparities in CR referral and participation rates among individuals from rural communities and racial and ethnic minority groups with coronary heart disease (CHD) when compared to the general population. METHODS: A systematic search of standard databases including MedlLine, PubMed, and Cochrane databases was conducted using keywords that included cardiac rehabilitation, women, race and ethnicity, disparities, and rural populations. Twenty-eight clinical studies from 1990 to 2017 were selected and included 478,955 patients with CHD. RESULTS: The majority of available clinical studies showed significantly lower CR referral and participation rates among individuals from rural communities, women, and racial and ethnic groups when compared to the general population. Similar to geographic region, socioeconomic status (SES) appears to directly impact the use of CR programs. Patients of lower SES have significantly lower CR referral and participation rates than patients of higher SES. CONCLUSIONS: Data presented underscores the need for systematic referrals using electronic health records for patients with CHD in order to increase overall CR referral and participation rates of minority populations and other vulnerable groups. Educational programs that target healthcare provider biases towards racial and ethnic groups may help attenuate observed disparities. Alternative modalities such as home-based and internet-based CR programs may also help improve CR participation rates among vulnerable populations.

Cor triatriatum sinister identified after new onset atrial fibrillation in an elderly man.

A 73-year-old man with new onset atrial fibrillation with rapid ventricular response underwent transthoracic echocardiography that revealed an echogenic linear structure along the left atrium, suggestive of cor triatriatum sinister (CTS). CTS was confirmed with transesophageal echocardiography which demonstrated a proximal accessory atrium receiving pulmonary venous flow separated from a distal true atrium by a fibromuscular membrane with a large fenestration allowing flow between the chambers. In CTS, the left atrium is divided into proximal and distal chambers by a fenestrated fibromuscular septum. This cardiac anomaly accounts for 0.1% of cases of congenital heart disease and rarely presents in adults. CTS is primarily diagnosed with echocardiography and is associated with left atrial enlargement and development of atrial fibrillation. Treatment options depend on size of the communication between proximal and distal chambers, the gradient across the membrane, and the position of pulmonary veins. In some instances, surgical resection of the membrane that divides the left atrium is warranted.
