Polycythemia Vera Presenting as ST-Segment Elevation Myocardial Infarction
An 80-year-old woman with a history of hypertension, pre-diabetes, chronic kidney disease (stage 3b), and a remote ischemic stroke without residual deficits presented to the emergency department complaining of several hours of epigastric discomfort and malaise. An electrocardiogram (EKG) performed at triage revealed normal sinus rhythm with>1 mm ST segment elevation in leads V4-6 and lead 1, reciprocal ST depression in aVR, and Q waves in V1 and V2 (Figure 1). The troponin I was elevated to 1.66 ng/mL (reference range

Prognostic value of preoperative electrocardiography in predicting myocardial injury after vascular surgery
CONCLUSION: This study confirmed that preoperative ECG abnormalities are frequent in patients undergoing high-risk vascular surgery. However, we did not find evidence supporting relation between preoperative ECG abnormalities and postoperative adverse cardiac outcomes in high risk patients.PMID:35344585 | DOI:10.33963/KP.a2022.0085

Data-driven clustering supports adaptive remodeling of athlete's hearts: An echocardiographic study from the Taipei Summer Universiade
CONCLUSION: Hierarchical clustering could analyze complicated multiparametric interactions among numerous echocardiography-derived phenotypes to discern the adaptive propensity of the athlete's heart. The endorsement or generation of hypotheses by a data-driven approach can be applied to various domains.PMID:34740491 | DOI:10.1016/j.jfma.2021.10.017

Early rehabilitation after stroke: relationship between the heart rate variability and functional outcome
ConclusionsThe presence of autonomic cardiovascular dysregulation in patients with subacute stroke was associated with adverse functional outcome after the early post ‐stroke rehabilitation.

Determining Safe Participation in Aerobic Exercise Early After Stroke Through a Graded Submaximal Exercise Test.
CONCLUSION: A graded submaximal exercise test without ECG but with symptom monitoring and conservative heart rate and perceived exertion endpoints may facilitate safe exercise intensities early after stroke. Symptom-limited exercise testing with ECG is still recommended when progressing to higher-intensity exercise. IMPACT: Concerns about cardiovascular risk are a barrier to physical therapists implementing aerobic exercise in stroke rehabilitation. This study showed that, in the absence of access to exercise testing with ECG, submaximal testing with conservative heart rate and perceived exertion endpoints and symptom...
