INTRODUCTION Recent studies have reported the efficacy of sheathless percutaneous coronary intervention (PCI) using hydrophilic-coated 5-Fr guiding catheters that are one to two Fr sizes smaller in diameter than the corresponding introducer sheath (virtual 3-Fr PCI). However, the limited number of shapes of hydrophilic-coated guiding catheters occasionally makes them difficult to engage and con...

INTRODUCTION Various studies have reported poor awareness and knowledge of dentistry in the Nigerian population. There is, however, paucity of information assessing the knowledge and awareness of medical doctors/students and nurses about dentistry. The present study is aimed at determining the knowledge and awareness of medical doctors/students and nurses about dentistry. METHODS Self-adminis...

Older patients with angina represent a patient group with many clinical challenges. Coronary artery disease is particularly common in older patients and the mortality associated with cardiovascular disease is high. Furthermore, diagnosis can be difficult and comorbidities are common. Unfortunately, evidence from clinical trials based on this group of patients is limited and current treatment gu...

PURPOSE The study aims to clinically validate the defining characteristics (DCs) of the nursing diagnosis (ND) of Activity Intolerance for patients with ischemic heart disease and refractory angina. METHODS Cross-sectional study was used, involving 22 patients with ND of Activity Intolerance. The Fehring method was used to validate the ND. FINDINGS Most DCs presented reliability indexes bet...

Takagi et al, have reported the findings of a nationwide multicentre Japanese registry on the arrhythmic risk of provocative tests of coronary artery spasm (CAS) in all comers with angiographically documented vasospastic angina (VSA). They recruited a total of 1246 patients who, after the test, were followed for a median period of 32 months in order to quantify major acute cardiac events (MACEs...

Diagnostic usefulness of 99mTc-MIBI myocardial SPECT at rest was examined in 39 cases of coronary vasospastic angina pectoris who were diagnosed by a positive reaction to ergonovine provocation. SPECT was performed 45 minutes (early image) and 3 hours (delayed image) after the intravenous injection of approximately 600 MBq of MIBI. Decrease in accumulation was ranked by four defect scores (0: n...

Refractory angina presents a major clinical challenge for everyday medical practice. Despite the widespread use of statins and improvements in revascularization techniques, a substantial proportion of patients with preserved left ventricular function and no life-threatening arrhythmias remain symptomatic, with severe debilitating angina. Because the rate of major cardiac events in this populati...
