Background— Heart failure with reduced ejection fraction and obstructive sleep apnea (OSA), 2 states of increased metabolic demand sympathetic nervous system activation, often coexist. Continuous positive airway pressure (CPAP), which alleviates OSA, can improve ventricular function. It is unknown whether this due to altered oxidative metabolism or presynaptic nerve We hypothesized that short-term (6–8 weeks) CPAP in patients OSA heart would myocardial function energetics. Methods Results—...
Abstract Background When crossing into the distal true lumen fails during chronic total occlusion (CTO) percutaneous coronary intervention (PCI), subintimal plaque modification (SPM) is often performed to restore antegrade flow and facilitate subsequent lesion recanalization. Methods Between January 2012 May 4, 2019, 4,659 CTO PCIs were included in PROGRESS‐CTO registry, of which 935 (20%) had a prior unsuccessful attempt. Of those patients, 119 (13%) SPM. We analyzed outcomes 58 SPM...
Chronic total occlusion (CTO) percutaneous coronary intervention (PCI) has significantly evolved in recent years.
To investigate the perceptions of interventional cardiologists (IC) regarding frequency, impact, and management strategies percutaneous coronary intervention (PCI) complications.The ICs PCI complications have received limited study.Online survey on complications: 46 questions were distributed via email lists Twitter to ICs.Of 11,663 contacts, 821 responded (7% response rate): 60% from United States median age was 46-50 years. Annual case numbers <100 (26%), 100-199 (37%), 200-299 (21%), ≥300...
Digital subtraction and an experimental system for line-scanned radiography were used to image the bifurcations of carotid arteries. The subtracted images obtained before after injections contrast media. anatomy extracranial arteries was demonstrated in most patients, verified by selective catheter arteriograms. Unsuccessful studies attributed improper timing while obtaining images, venous occlusion. Artifacts produced motion limit temporal method.
The impact of peripheral artery disease (PAD) in patients undergoing chronic total occlusion (CTO) percutaneous coronary intervention (PCI) has received limited study. We reviewed 3999 CTO PCIs performed 3914 between 2012 and 2018 at 25 centers, 14% whom had a history PAD. compared the clinical angiographic characteristics procedural outcomes with versus without Patients PAD were older (67 ± 9 vs 64 10 years, P < .001) higher prevalence cardiovascular risk factors. They also more complex...
The study aim was to assess current procedural strategies and perceptions for percutaneous coronary intervention (PCI) involving bifurcations.
Limited data exist regarding discrimination against interventional cardiologists (ICs) across different career stages. Methods: We performed an online, anonymous, international survey of ICs. Physicians with less than 10 years in practice, 11 to 20 years, and over 21 were categorized as early, middle, late career, respectively. Results: The had 445 participants: 190 early 124 middle 131 career. Early respondents likely practice the US (45% vs 65% 79%, p<0.001) identify non-Hispanic white...
