Early detection and treatment of cardiovascular disease are crucial for patient survival and long-term health. Despite advances in cardiovascular disease biomarkers, the prevalence of cardiovascular disease continues to increase worldwide as the global population ages. To address this problem, novel biomarkers that are more sensitive and specific to cardiovascular diseases must be developed and incorporated into clinical practice. Exosomes are promising biomarkers for cardiovascular disease. These small vesicles are produced and released into body fluids by all cells and carry specific information that can be correlated with disease progression.

With the increasing availability of 2-dimensional ultrasonography and advanced Doppler capabilities, a quick, simplified, and integrated stepwise approach to shock using critical care echocardiography is proposed. Evidence supports the feasibility and usefulness of critical care echo-cardiography in enhancing diagnostic accuracy for shock, but there is a lack of systematic application of the technology in patients with undifferentiated shock. The proposed approach begins with the use of noninvasive ultrasonography with pulsed-wave Doppler capability to determine the flow state by measuring the velocity time integral of the left ventricular outflow tract. This narrative review explores the use left ventricular outflow tract velocity time integral, velocity time integral variation, limited visceral organ Doppler, and lung ultrasonography as a systematic approach for patients with undifferentiated shock.</p>","PeriodicalId":48680,"journal":{"name":"Texas Heart Institute Journal","volume":"50 5","pages":""},"PeriodicalIF":0.9,"publicationDate":"2023-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10658166/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41240023","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
