A Multiple-Model Generalisation of Updating Clinical Prediction Models (2018)
Journal Article
Mamas. (2018). A Multiple-Model Generalisation of Updating Clinical Prediction Models. Statistics in Medicine, 1343-1358. https://doi.org/10.1002/sim.7586

There is growing interest in developing clinical prediction models (CPMs) to aid local healthcare decision-making. Frequently, these CPMs are developed in isolation across different populations, with repetitive de novo derivation a common modelling s...

Effect of Gender On Unplanned Readmissions After Percutaneous Coronary Intervention (From The Nationwide Readmissions Database) (2018)
Journal Article
Kwok, C., Potts, J., Gulati, M., Alasnag, M., Rashid, M., Shoaib, A., …Mamas, M. (2018). Effect of Gender On Unplanned Readmissions After Percutaneous Coronary Intervention (From The Nationwide Readmissions Database). American Journal of Cardiology, 810-817. https://doi.org/10.1016/j.amjcard.2017.12.032

Women who undergo percutaneous coronary intervention (PCI) are at higher risk of adverse outcomes compared with men, but it is unknown whether gender affects early unplanned rehospitalization. We analyzed 832,753 patients who underwent PCI from 2013...

Comorbidity health pathways in heart failure patients: A sequences-of-regressions analysis using cross-sectional data from 10,575 patients in the Swedish Heart Failure Registry (2018)
Journal Article
Mamas, & Solis-Trapala. (2018). Comorbidity health pathways in heart failure patients: A sequences-of-regressions analysis using cross-sectional data from 10,575 patients in the Swedish Heart Failure Registry. PLoS Medicine, https://doi.org/10.1371/journal.pmed.1002540

Background
Optimally treated heart failure (HF) patients often have persisting symptoms and poor health-related quality of life. Comorbidities are common, but little is known about their impact on these factors, and guideline-driven HF care remains...

Operator volume is not associated with mortality following Percutaneous Coronary Intervention: insights from the British Cardiovascular Intervention Society registry (2018)
Journal Article
Mamas. (2018). Operator volume is not associated with mortality following Percutaneous Coronary Intervention: insights from the British Cardiovascular Intervention Society registry. European Heart Journal, 1623-1634. https://doi.org/10.1093/eurheartj/ehy125

Aims
The relationship between operator volume and outcomes for percutaneous coronary intervention (PCI) has been studied in the past, but recent analyses of national data covering the modern radial, acute coronary syndrome-dominant era are limited....

Increasing socio-economic gap between the young and old: temporal trends in health and overall deprivation in England by age, sex, urbanity and ethnicity, 2004 to 2015 (2018)
Journal Article
Mamas. (2018). Increasing socio-economic gap between the young and old: temporal trends in health and overall deprivation in England by age, sex, urbanity and ethnicity, 2004 to 2015. Journal of Epidemiology and Community Health, 636-644. https://doi.org/10.1136/jech-2017-209895

Background: At a low geographical level, little is known about the associations between population characteristics and deprivation, and their trends, which would be directly affected by the house market, labour pressures and government policies. We d... Read More about Increasing socio-economic gap between the young and old: temporal trends in health and overall deprivation in England by age, sex, urbanity and ethnicity, 2004 to 2015.

Multimorbidity and survival for patients with acute myocardial infarction in England and Wales: Latent class analysis of a nationwide population-based cohort (2018)
Journal Article
Mamas. (2018). Multimorbidity and survival for patients with acute myocardial infarction in England and Wales: Latent class analysis of a nationwide population-based cohort. PLoS Medicine, e1002501. https://doi.org/10.1371/journal.pmed.1002501

Background
There is limited knowledge of the scale and impact of multimorbidity for patients who have had an acute myocardial infarction (AMI). Therefore, this study aimed to determine the extent to which multimorbidity is associated with long-term...

JACC. Cardiovascular interventions, 482-492. https://doi.org/10.1016/j.jcin.2017.12.020

Objectives
Using the British Cardiovascular Intervention Society percutaneous coronary intervention (PCI) database, access site choice and outcomes of patients undergoing PCI with previous coronary artery bypass grafting (CABG) were studied.

Back... Read More about Vascular access site and outcomes in 58,870 patients undergoing PCI with a previous history of coronary bypass surgery: results from the British Cardiovascular Interventions Society National database.

The effect of pre-procedure sublingual nitroglycerin on radial artery diameter and Allen’s test outcome - relevance to transradial catheterization (2018)
Journal Article
Chong, A., Lo, T., George, S., Ratib, K., Mamas, M., & Nolan, J. (2018). The effect of pre-procedure sublingual nitroglycerin on radial artery diameter and Allen’s test outcome - relevance to transradial catheterization. Cardiovascular Revascularization Medicine, 19(2), 163-167. https://doi.org/10.1016/j.carrev.2017.07.016

Background
The radial artery is increasingly used for cardiac procedures, but is a relatively small vessel that is prone to spasm when instrumented. Intra-arterial nitroglycerine has been shown to reduce radial spasm but first requires arterial acce...

Chronic morbidity, deprivation and primary medical care spending in England in 2015-16: a cross-sectional spatial analysis (2018)
Journal Article
Mamas. (2018). Chronic morbidity, deprivation and primary medical care spending in England in 2015-16: a cross-sectional spatial analysis. BMC Medicine, https://doi.org/10.1186/s12916-017-0996-0

Background
Primary care provides the foundation for most modern health-care systems, and in the interests of equity, it should be resourced according to local need. We aimed to describe spatially the burden of chronic conditions and primary medical...
