Today's coronary care unit patients include those with complicated and uncomplicated myocardial infarction, decompensated heart failure and frank cardiogenic shock, severe valvular heart disease, high-grade conduction disturbances, and incessant ventricular arrhythmias. Increasingly in modern medicine, these conditions are not seen in isolation but rather in connection with a series of additional medical comorbidities. Increased life expectancy results in an increase in the prevalence of chronic cardiovascular diseases and an increased demand for health care services. ⋯ This might, however, require a more active remote surveillance than the one tested in this study. Privacy- and security-related aspects are major components of building trust and confidence in telemedicine systems. In telecardiology, the real-time interactive telemedicine model with 24/7 service has potential superior performance compared with a store-and-forward telemedicine model.

Significance of T-wave amplitude and dynamics at the time of reperfusion in patients with acute ST-segment elevation myocardial infarction treated with primary percutaneous coronary intervention.
Peri-interventional T-wave changes may reflect the microvascular reperfusion status and potentially carry early independent, prognostic information in patients with ST-elevation myocardial infarction (STEMI) treated with primary percutaneous coronary intervention (PCI). ⋯ Large T-wave amplitudes in static pre- and post-PCI ECGs are associated with delayed microvascular reperfusion, whereas the dynamic development of more negative T waves during PCI is associated with earlier microvascular reperfusion. However, in the acute setting, T waves provide little incremental information when compared to ST parameters available in the per-interventional phase.

Although the presence and severity of electrocardiographic (ECG) left ventricular hypertrophy (LVH) have been associated with an increased risk of cardiovascular (CV) morbidity and mortality, the relationship of regression of ECG LVH during antihypertensive therapy to CV risk has only recently been examined. ⋯ Regression of ECG LVH by Cornell product and/or Sokolow-Lyon voltage criteria during antihypertensive therapy is associated with lower likelihoods of CV morbidity and mortality, all-cause mortality, and new-onset diabetes, independent of blood pressure lowering and treatment modality in essential hypertension. These findings suggest that antihypertensive therapy targeted at regression or prevention of ECG LVH may improve prognosis.
