The monitoring of peripheral circulation, as indicated by the capillary refill time, is a sensitive and accurate method of assessing the microcirculatory status of the body. It is a widely used tool for the evaluation of critically ill patients, the guidance of therapeutic interventions, and the assessment of prognosis. In recent years, there has been a growing emphasis on microcirculation monitoring which has led to an increased focus on capillary refill time.

: Impaired systemic tissue oxygenation and microvascular perfusion are associated with adverse outcomes in patients with acute respiratory distress syndrome (ARDS). Tissue oxygenation and microvascular reactivity, assessed by using near-infrared spectroscopy (NIRS), are correlated with disease severity in critically ill populations. This study aimed to detect alterations in these factors and their ability to predict outcomes in patients with ARDS.

Department of Internal Medicine and Division of Cardiology, Baylor Scott and White, Temple, TX, United States of America. Electronic address:

Background: Angina with no obstructive coronary artery disease (ANOCA) occurs in approximately 40 % of patients who undergo diagnostic coronary angiography for symptoms of angina. Coronary physiology assessment (CPA) is a guideline proven method to assess and diagnose these patients for an effective treatment strategy. There is currently no data regarding optimal wire or sensor position for CPA using bolus coronary thermodilution.

The advancements in cardiovascular imaging over the past two decades have been significant. The miniaturization of ultrasound devices has greatly contributed to their widespread adoption in operating rooms and intensive care units. The integration of AI-enabled tools has further transformed the field by simplifying echocardiographic evaluations and enhancing the reproducibility of hemodynamic measurements, even for less experienced operators.

The role of non-invasive stress testing in the diagnosis of coronary microvascular disease.

Cardiovasc Revasc Med

December 2024

Department of Cardiology, Tel Aviv Sourasky Medical Center, affiliated with the School of Medicine, Tel Aviv University, Israel.

Background: Angina with non-obstructive coronary artery disease (ANOCA) is commonly observed in patients with stable angina undergoing coronary angiography. Current guidelines recommend non-invasive stress testing as the first step in diagnosing coronary microvascular disease (CMD). This study aims to evaluate the diagnostic value of non-invasive stress testing in patients invasively diagnosed with CMD.
