Arterial Ultrasonography and Tonometry as Adjuncts to Cardiovascular Risk Stratification

Arterial ultrasonography and tonometry as adjuncts to cardiovascular risk stratification.

Myocardial infarction and stroke often occur without prior warning in asymptomatic individuals. Identifying individuals at risk is important for cost-effective use of preventive therapies. Algorithms based on risk factors statistically associated with cardiovascular events classify individuals into high-risk, intermediate-risk, or low-risk categories. However, more than one-third of adults in t...

Ultrasonography and Tonometry for the Assessment of Human Arterial Stiffness

Cardiovascular Risk Stratification: From Phenotype to Genotype?

DOI: 10.5935/abc.20180010 Cardiovascular risk scores, such as the Framingham score, have been strongly recommended by clinical guidelines on the assessment of cardiovascular risk.1 However, several studies have shown limitations for their use,2,3 particularly in patients at intermediate risk, young patients with a definite family history, and women. Among different tools aimed at improving risk...

Augmentation Index Derived from Peripheral Arterial Tonometry Correlates with Cardiovascular Risk Factors

Background. Augmentation index (AIx) is traditionally obtained from pressure waveforms via arterial applanation tonometry. We sought to evaluate the association between AIx obtained from peripheral arterial tonometry (PAT) with cardiovascular risk factors (CRF) and coronary artery disease (CAD). Methods. 186 patients were enrolled in the study. The presence or absence of CRFs and CAD was assess...

Arterial tonometry in the classroom

The study of hemodynamic physiology utilizing traditional methods presents many challenges and limitations to educators. The goal of the educator is to provide the student with an adequate understanding of the basic hemodynamic anatomy and physiology governing blood flow, cardiac cycle and associated Korotkoff sounds, and the pathophysiology of vessel-related diseases. Several teachable moments...
