Aims: In light of recent advances in imaging techniques, molecular understanding and therapeutic options in hypertrophic cardiomyopathy (HCM), we performed a systematic review of current guidelines for the diagnosis and management of HCM in order to identify consensus and discrepant areas in the clinical practice guidelines.

Methods And Results: We systematically reviewed the English language guidelines and recommendations for the management of HCM in adults. MEDLINE and EMBASE databases were searched for guidelines published in the last 10 years.

Dilated cardiomyopathy (DCM) is extensively discussed in numerous expert consensus documents and international guidelines, with differing recommendations. To support clinicians in daily practice and decision-making, we conducted a systematic review of key guidelines and recommendations concerning the diagnosis and clinical management of DCM. Our research encompassed MEDLINE and EMBASE databases for relevant articles published, as well as the websites of relevant scientific societies.

Background: Hyperlipidemia is a major cardiovascular disease (CVD) risk factor, but limited data on its mortality trends in CVD over time. We assessed annual hyperlipidemia-related CVD mortality trends in the United States, including the COVID-19 pandemic's impact.

Methods And Results: Mortality data were obtained from CDC repository between 1999 and 2020 among patients ≥15 years old, using ICD-10 codes hyperlipidemia (E78.

Article Synopsis
  • Drug-induced long QT syndrome (diLQTS) is a serious side effect of over 150 medications that can lead to dangerous heart conditions; the study aimed to validate a genetic risk score for predicting this syndrome.
  • Researchers analyzed data from a large cohort of patients taking high-risk QT-prolonging drugs and found that the risk score was significantly associated with diLQTS in White patients, indicating a higher likelihood of QT prolongation during treatment.
  • Although the risk score showed promise in identifying high-risk individuals, the study was underpowered to confirm its effectiveness across African American and Asian populations, highlighting the need for larger sample sizes in diverse groups.

Precision medicine, which among other aspects includes an individual's genomic data in diagnosis and management, has become the standard-of-care for Mendelian cardiovascular disease (CVD). However, early identification and management of asymptomatic patients with potentially lethal and manageable Mendelian CVD through screening, which is the promise of precision health, remains an unsolved challenge. The reduced costs of genomic sequencing have enabled the creation of biobanks containing in-depth genetic and health information, which have facilitated the understanding of genetic variation, penetrance, and expressivity, moving us closer to the genotype-first screening of asymptomatic individuals for Mendelian CVD.
