Journal Article
Mamas. (2017). Geographical epidemiology of health and overall deprivation in England, its changes and persistence from 2004 to 2015: a longitudinal spatial population study. Journal of epidemiology and community health, 140-147. https://doi.org/10.1136/jech-2017-209999

Background: Socio-economic deprivation is a key determinant for health. In England, the Index of Multiple Deprivation (IMD) is a widely used composite measure of deprivation. However, little is known about its spatial clustering or persistence acros...

Impact of anaemia on acute stroke outcomes depends on the type of anaemia: Evidence from a UK stroke register (2017)
Journal Article
Mamas. (2017). Impact of anaemia on acute stroke outcomes depends on the type of anaemia: Evidence from a UK stroke register. Journal of the Neurological Sciences, 26-30. https://doi.org/10.1016/j.jns.2017.09.047

AbstractBackground Previous research has demonstrated an association between anaemia and poor outcomes in acute stroke. This study aimed to assess the impact of anaemia on stroke by anaemia subtype. Methods Data from a prospective UK Regional Stroke... Read More about Impact of anaemia on acute stroke outcomes depends on the type of anaemia: Evidence from a UK stroke register.

A Novel UK Prognostic Model for 30-day Mortality following Transcatheter Aortic Valve Implantation (2017)
Journal Article
Mamas. (2017). A Novel UK Prognostic Model for 30-day Mortality following Transcatheter Aortic Valve Implantation. Heart, 1109-1116. https://doi.org/10.1136/heartjnl-2017-312489

Objective Existing clinical prediction models (CPM) for short-term mortality after transcatheter aortic valve implantation (TAVI) have limited applicability in the UK due to moderate predictive performance and inconsistent recording practices across...

Longitudinal deformation bench testing using a coronary artery model: a new standard? (2017)
Journal Article
Mamas. (2017). Longitudinal deformation bench testing using a coronary artery model: a new standard?. Open Heart, https://doi.org/10.1136/openhrt-2016-00053

Objectives To compare susceptibility of five different stent platforms with longitudinal stent deformation (LSD) using a clinically relevant bench testing model simulating both short and long malapposed lengths. Background Recent data suggest that de... Read More about Longitudinal deformation bench testing using a coronary artery model: a new standard?.

Advanced glycation end products reduce the calcium transient in cardiomyocytes by increasing production of reactive oxygen species and nitric oxide (2017)
Journal Article
Mamas. (2017). Advanced glycation end products reduce the calcium transient in cardiomyocytes by increasing production of reactive oxygen species and nitric oxide. FEBS Open Bio, 1672 -1685. https://doi.org/10.1002/2211-5463.12284

Advanced glycation end products (AGE) are central to the development of cardiovascular complications associated with diabetes mellitus. AGE may alter cellular function through cross-linking of cellular proteins or by activating the AGE receptor (RAGE...

Objectives This study sought to determine the risk factors for post-transcatheter aortic valve replacement (TAVR) dialysis and to determine the impact of pre-TAVR or post-TAVR dialysis on mortality. Background TAVR is now established as an alter... Read More about Dialysis following Transcatheter Aortic Valve Implantation: risk factors and outcomes: An analysis from the UK TAVI Registry.

Relative survival following transcatheter aortic valve implantation: how do TAVI patients fare relative to the general population? (2017)
Journal Article
Mamas. (2017). Relative survival following transcatheter aortic valve implantation: how do TAVI patients fare relative to the general population?. Journal of the American Heart Association Cardiovascular and Cerebrovascular Disease, https://doi.org/10.1161/JAHA.117.007229

Background Transcatheter aortic valve implantation (TAVI) is indicated for patients with aortic stenosis who are intermediate-high surgical risk. Although all-cause mortality rates after TAVI are established, survival attributable to the procedure i...
