To derive specific maximal heart rate (HRmax) prediction equations for a coronary artery disease (CAD) population based upon status of β-blocker (BB) therapy and to compare these to prior HRmax equations (Fox and Brawner-specific for CAD).
We retrospectively reviewed stress echocardiogram treadmill tests in patients with CAD, dividing subjects into 3 groups based upon BB use on test day: not prescribed BB therapy (no BB group; n = 110); held for 12 to 24 hr prior (held BB group; n = 155); and continued taking (took BB group; n = 72).
Derived HRmax equations for our CAD population were no BB = 200 - 0.

Polymer-free drug-eluting stents (PF-DES) were designed with the expectation of avoiding late restenosis and thrombosis related to the polymer used in traditional DES platforms. Furthermore, due to similarities with bare metal stents after drug elution, PF-DES has been considered as particularly suitable for patients at high bleeding risk. A variety of PF-DES platforms have been clinically tested.

Although cancer patients (CPs) are increasingly likely to visit emergency department (ED), no population-based study has compared the characteristics of CPs and non-cancer patients (NCPs) who visit the ED and examined factors associated with hospitalization via the ED. In this study, we (1) compared characteristics and diagnoses between CPs and NCPs who visited the ED in a cancer center or general hospital; (2) compared characteristics and diagnoses between CPs and NCPs who were hospitalized via the ED in a cancer center or general hospital; and (3) investigated important factors associated with such hospitalization.
We analyzed patient characteristic and diagnosis [based on International Classification of Diseases-9 (ICD-9) codes] data from the ED of a comprehensive cancer center (MDACC), 24 general EDs in Harris County, Texas (HCED), and the National Hospital Ambulatory Medical Care Survey (NHAMCS) from 1/1/2007-12/31/2009.

Sleep characteristics are associated with incident cardiovascular diseases (CVD), but there is a lack of studies on the association between sleep characteristics and incidence/progression of coronary artery calcification (CAC).
In the Heinz Nixdorf Recall Study, a population-based cohort study in Germany, CAC was assessed by electron-beam tomography at baseline and at 5-year follow-up. In an analysis set of 3043 subjects (age at baseline 45-74 years; 47% men), we fitted logistic and linear regression models to assess associations between self-rated sleep characteristics (nocturnal and total sleep duration; napping; various sleep disorders) and CAC incidence/CAC progression.

Minimally invasive mitral valve repair may be associated with prolonged cardioplegic arrest times and ischemic reperfusion injury. Intravenous (propofol) and volatile (sevoflurane) anesthesia are used routinely during cardiac surgery and are thought to provide cardioprotection; however, the individual contribution of each regimen to cardioprotection is unknown. Therefore, the authors sought to compare the cardioprotective effects of propofol and sevoflurane anesthesia in patients undergoing minimally invasive mitral valve repair.

Acute ST-segment elevation myocardial infarction (STEMI) typically arises from total occlusion of an epicardial coronary artery, most often due to atherosclerotic plaque rupture/erosion and subsequent thrombus formation. Granted this, important angiographic information for patients presenting with STEMI is not only about the status of infarct-related artery (IRA) but also about the atherosclerotic disease burden and disease severity of non-IRA vessels. Previous studies have reported that multivessel (MV) coronary artery disease (CAD) is found in approximately 50% of patients with STEMI undergoing primary percutaneous coronary intervention (PCI) [1,2].

The percutaneous transradial artery approach for coronary angiography and intervention has been recognized as a safe and effective method, however, it is limited for endovascular therapy (EVT) for femoro-popliteal artery because of lack of devices with longer shaft. Herein, we report two EVT cases for superficial femoral artery disease treated with a long shaft balloon through the radial artery. Although femoro-popliteal artery intervention with this approach has several limits for available devices and technical issues, it is effective for particular patients who are impossible in EVT with femoral artery approach.
