Outcome disparities in acute coronary syndrome patients from rural versus urban settings: A narrative review of causes, and strategies to minimize them.

Acute coronary syndrome (ACS) remains an important cause of morbidity and mortality worldwide. Critical elements of improving outcomes in ACS patients include timely access to acute care including prompt revascularization if indicated, and subsequent ongoing secondary prevention and risk factor modification, ideally with cardiovascular specialists. It is being increasingly realized that ACS patients from rural settings suffer from inferior outcomes compared to their urban counterparts due to factors such as delayed diagnosis, delayed access to acute care, and less accessibility to specialized follow up. This narrative review will examine the importance of timely access to care in ACS patients, particularly in ST-elevation myocardial infarction; how barriers in access to care affects outcomes in various rural populations; and strategies that have been shown to improve such access, and therefore hopefully achieve more equitable health outcomes compared to patients who live in urban settings.

Impact of biological sex on valvular heart disease, interventions, and outcomes.

Valvular heart disease (VHD) is common, affecting >14% of individuals aged >75, and is associated with morbidity, including heart failure and arrhythmia, and risk of early mortality. Increasingly, important sex differences are being found between males and females with VHD. These sex differences can involve the epidemiology, pathophysiology, presentation, diagnosis, and outcomes of the disease. Females are often disadvantaged, and female sex has been shown to be associated with delayed diagnosis and inferior outcomes in various forms of VHD. In addition, the unique pathophysiologic state of pregnancy is associated with increased risk for maternal and fetal morbidity and mortality in many forms of VHD. Therefore, understanding and recognizing these sex differences, and familiarity with the attendant risks of pregnancy and management of pregnant females with VHD, is of great importance for any primary care or cardiovascular medicine practitioner caring for the female patient. This review will outline sex differences in aortic, mitral, pulmonic, and tricuspid VHD, with particular focus on differences in pathophysiology, clinical presentation, and outcomes. In addition, the pathophysiology and management implications of pregnancy will be discussed.
