RESUMEN
PURPOSE OF REVIEW: Wearable technology is rapidly evolving and the data that it can provide regarding an individual's health is becoming increasingly important for clinicians to consider. The purpose of this review is to help inform health care providers of the benefits of smartwatch interrogation, with a focus on reviewing the various parameters and how to apply the data in a meaningful way. RECENT FINDINGS: This review details interpretation of various parameters found commonly in newer smartwatches such as heart rate, step count, ECG, heart rate recovery (HRR), and heart rate variability (HRV), while also discussing potential pitfalls that a clinician should be aware of. Smartwatch interrogation is becoming increasingly relevant as the continuous data it provides helps health care providers make more informed decisions regarding diagnosis and treatment. For this reason, we recommend health care providers familiarize themselves with the technology and integrate it into clinical practice.

Importance: The European Society of Cardiology (ESC) 0/1-hour algorithm is a validated high-sensitivity cardiac troponin (hs-cTn) protocol for emergency department patients with possible acute coronary syndrome. However, limited data exist regarding its performance in patients with known coronary artery disease (CAD; prior myocardial infarction [MI], coronary revascularization, or ≥70% coronary stenosis). Objective: To evaluate and compare the diagnostic performance of the ESC 0/1-hour algorithm for 30-day cardiac death or MI among patients with and without known CAD and determine if the algorithm could achieve the negative predictive value rule-out threshold of 99% or higher. Design, Setting, and Participants: This was a preplanned subgroup analysis of the STOP-CP prospective multisite cohort study, which was conducted from January 25, 2017, through September 6, 2018, at 8 emergency departments in the US. Patients 21 years or older with symptoms suggestive of acute coronary syndrome without ST-segment elevation on initial electrocardiogram were included. Analysis took place between February and December 2022. Interventions/Exposures: Participants with 0- and 1-hour high-sensitivity cardiac troponin T (hs-cTnT) measures were stratified into rule-out, observation, and rule-in zones using the ESC 0/1-hour hs-cTnT algorithm. Main Outcomes and Measures: Cardiac death or MI at 30 days determined by expert adjudicators. Results: During the study period, 1430 patients were accrued. In the cohort, 775 individuals (54.2%) were male, 826 (57.8%) were White, and the mean (SD) age was 57.6 (12.8) years. At 30 days, cardiac death or MI occurred in 183 participants (12.8%). Known CAD was present in 449 (31.4%). Among patients with known CAD, the ESC 0/1-hour algorithm classified 178 of 449 (39.6%) into the rule-out zone compared with 648 of 981 (66.1%) without CAD (P < .001). Among rule-out zone patients, 30-day cardiac death or MI occurred in 6 of 178 patients (3.4%) with known CAD and 7 of 648 (1.1%) without CAD (P < .001). The negative predictive value for 30-day cardiac death or MI was 96.6% (95% CI, 92.8-98.8) among patients with known CAD and 98.9% (95% CI, 97.8-99.6) in patients without known CAD (P = .04). Conclusions and Relevance: Among patients with known CAD, the ESC 0/1-hour hs-cTnT algorithm was unable to safely exclude 30-day cardiac death or MI. This suggests that clinicians should be cautious if using the algorithm in patients with known CAD. The negative predictive value was significantly higher in patients without a history of CAD but remained less than 99%.

Cardiac rehabilitation following transcatheter aortic valve replacement (TAVR) is associated with improved outcomes; however, it remains relatively underutilized in this patient population. As part of a quality improvement initiative, we sought to increase the rate of cardiac rehabilitation referral after TAVR at our institution. We designed and implemented a multidisciplinary program that included education of cardiothoracic surgery providers discharging post-TAVR patients on the benefits of cardiac rehabilitation with participation of cardiac rehabilitation personnel during discharge rounds with the surgical team. The study period was defined as 12 months prior to and 6 months following the implementation of the education program. Overall referral rates increased from 5% to 56% ( P < 0.0001), and referrals placed before hospital discharge increased from 0.8% to 53% ( P < 0.0001) over the study period. In conclusion, a combination of education regarding the benefits of cardiac rehabilitation and cardiac rehabilitation personnel participation in discharge rounds significantly increased referral to cardiac rehabilitation after TAVR.

It is clear that existing cardiovascular disease is a major risk factor for COVID-19 and related adverse outcomes. In addition to acute respiratory syndrome, a large cohort also develop myocardial or vascular dysfunction, in part from inflammation and renin angiotensin system activation with increased sympathetic outflow, cardiac arrhythmias, ischemia, heart failure, and thromboembolic complications that portend poor outcomes related to COVID-19. We summarize recent information for hospitalists and internists on the front line of this pandemic regarding its cardiovascular impacts and management and the need for cardiovascular consultation.

OBJECTIVES: The aim of this study was to investigate the impact of spontaneous coronary artery dissection (SCAD) on 30-day readmission rates following hospitalization with acute myocardial infarction (AMI) using a national database. BACKGROUND: AMI in the setting of SCAD represents an uncommon type of myocardial infarction with limited data on short-term outcomes. METHODS: All hospitalizations with primary or index diagnoses of AMI from 2010 to 2015 in the Nationwide Readmissions Database were queried. The primary outcome was overall 30-day readmission rates in both SCAD and non-SCAD cohorts. Propensity score matching (1:2) was conducted. RESULTS: A total of 2,654,087 patients with AMI were included in the final analysis, of whom 1,386 (0.052%) were diagnosed with SCAD. SCAD was associated with a higher readmission rate in the SCAD cohort (12.3% vs. 9.9%; p = 0.022). The main causes of readmissions in the SCAD cohort were cardiac causes (80.6%), and AMI was the most common cardiac cause (44.8%), followed by chest pain (20.1%) and arrhythmia (12.7%). Among the SCAD readmissions, 50.6% patients were readmitted in the first week post-discharge, with 54.5% of AMI readmissions occurring in the first 2 days post-discharge. CONCLUSIONS: The incidence of 30-day readmission following AMI and SCAD is nontrivial and occurs early post-discharge. Most readmissions are due to cardiac causes, especially AMI. Targeted management approaches are needed to diminish the high rates of readmission and early recurrent AMI.

Today is an age of rapid digital integration, yet the capabilities of modern-day smartphones and smartwatches are underappreciated in daily clinical practice. Smartphones are ubiquitous, and smartwatches are very common and on the rise. This creates a wealth of information simply waiting to be accessed, studied and applied clinically, ranging from activity level to various heart rate metrics. This review considers commonly used devices, the validity and accuracy of the data they obtain and potential clinical application of the data.
