Variation in emergency percutaneous coronary intervention in ventilated patients in the UK: insights from a national database

Aims Pre-procedural ventilation is a marker of high risk in PCI patients. Causes include out-of-hospital cardiac arrest (OHCA) and cardiogenic shock. OHCA occurs in approximately 60,000 patients in the UK per annum. No consensus exists regarding the need/timing of coronary angiography ± revascularization without ST elevation. The aim was to describe the national variation in the rate of emergency PCI in ventilated patients. Methods and Results Using the UK national database for PCI in 2013, we identified all procedures performed as ‘emergency’ or ‘salvage’ for whom ventilation had been initiated before the PCI. Of the 92,589 patients who underwent PCI, 1342 (5.5%) fulfilled those criteria. There was wide variation in practice. There was no demonstrable relationship between the number of emergency PCI patients with pre-procedure ventilation per annum and (i) total number of PPCIs in a unit (r = −0.186), and (ii) availability of 24 h PCI, (iii) on-site surgical cover. Conclusion We demonstrated a wide variation in practice across the UK in rates of pre-procedural ventilation in emergency PCI. The majority of individuals will have suffered an OHCA. In the absence of a plausible explanation for this discrepant practice, it is possible that (a) some patients presenting with OHCA that may benefit from revascularization are being denied treatment and (b) procedures may be being undertaken that are futile. Further prospective data are needed to aid in production of guidelines aiming at standardized care in OHCA

Prevalence of Cardiovascular Disease in Patients With Potentially Curable Malignancies: A National Registry Dataset Analysis.

BACKGROUND: Although a common challenge for patients and clinicians, there is little population-level evidence on the prevalence of cardiovascular disease (CVD) in individuals diagnosed with potentially curable cancer. OBJECTIVES: We investigated CVD rates in patients with common potentially curable malignancies and evaluated the associations between patient and disease characteristics and CVD prevalence. METHODS: The study included cancer registry patients diagnosed in England with stage I to III breast cancer, stage I to III colon or rectal cancer, stage I to III prostate cancer, stage I to IIIA non-small-cell lung cancer, stage I to IV diffuse large B-cell lymphoma, and stage I to IV Hodgkin lymphoma from 2013 to 2018. Linked hospital records and national CVD databases were used to identify CVD. The rates of CVD were investigated according to tumor type, and associations between patient and disease characteristics and CVD prevalence were determined. RESULTS: Among the 634,240 patients included, 102,834 (16.2%) had prior CVD. Men, older patients, and those living in deprived areas had higher CVD rates. Prevalence was highest for non-small-cell lung cancer (36.1%) and lowest for breast cancer (7.7%). After adjustment for age, sex, the income domain of the Index of Multiple Deprivation, and Charlson comorbidity index, CVD remained higher in other tumor types compared to breast cancer patients. CONCLUSIONS: There is a significant overlap between cancer and CVD burden. It is essential to consider CVD when evaluating national and international treatment patterns and cancer outcomes

Determinants and outcomes of stroke following percutaneous coronary intervention by indication

Background and Purpose—Stroke after percutaneous coronary intervention (PCI) is a serious complication, but its determinants and outcomes after PCI in different clinical settings are poorly documented. Methods—The British Cardiovascular Intervention Society (BCIS) database was used to study 560 439 patients who underwent PCI in England and Wales between 2006 and 2013. We examined procedural-type specific determinants of ischemic and hemorrhagic stroke and the likelihood of subsequent 30-day mortality and in-hospital major adverse cardiovascular events (a composite of in-hospital mortality, myocardial infarction or reinfarction, and repeat revascularization). Results—A total of 705 stroke cases were recorded (80% ischemic). Stroke after an elective PCI or PCI for acute coronary syndrome indications was associated with a higher risk of adverse outcomes compared with those without stroke; 30-day mortality and major adverse cardiovascular events outcomes in fully adjusted model were odds ratios 37.90 (21.43–67.05) and 21.05 (13.25–33.44) for elective and 5.00 (3.96–6.31) and 6.25 (5.03–7.77) for acute coronary syndrome, respectively. Comparison of odds of these outcomes between these 2 settings showed no differences; corresponding odds ratios were 1.24 (0.64–2.43) and 0.63 (0.35–1.15), respectively. Conclusions—Hemorrhagic and ischemic stroke complications are uncommon, but serious complications can occur after PCI and are independently associated with worse mortality and major adverse cardiovascular events outcomes in both the elective and acute coronary syndrome setting irrespective of stroke type. Our study provides a better understanding of the risk factors and prognosis of stroke after PCI by procedure type, allowing physicians to provide more informed advice around stroke risk after PCI and counsel patients and their families around outcomes if such neurological complications occur
