Background: Benefits of cardiac rehabilitation (CR) programme components on attaining risk factor targets post-myocardial infarction (MI) and their predictive strength relative to patient characteristics remain unclear. We aimed to identify organizational and patient-level predictors of risk factor target attainment at one-year post-MI.

Methods: In this observational study data on CR organization at 78 Swedish CR centres was collected and merged with patient-level registry data (n = 7549).

Background: Many patients with heart failure with preserved ejection fraction (HFpEF) are undiagnosed, and UK general practice registers do not typically record heart failure (HF) subtype. Improvements in management of HFpEF is dependent on improved identification and characterisation of patients in primary care.

Aim: To describe a cohort of patients recruited from primary care with suspected HFpEF and compare patients in whom HFpEF was confirmed and refuted.

Background: Increased use of invasive coronary strategies in patients admitted to hospitals with on-site cardiac catheter laboratory (CCL) facilities has been reported, but the utilisation of invasive coronary strategies according to types of CCL facilities at the first admitting hospital and clinical outcomes is unknown.

Methods: We included 452,216 patients admitted with a diagnosis of non-ST-segment-elevation myocardial infarction (NSTEMI) in England and Wales from 2007 to 2015. The admitting hospitals were categorized into no-laboratory, diagnostic, and PCI hospitals according to CCL facilities.

We present the case of a 65-year-old woman who was referred urgently from primary care with worsening breathlessness for 3 weeks, associated with tachycardia and left bundle branch block (LBBB). She had a background of type 2 diabetes, asthma and hypertension. Initial ECG revealed atrial fibrillation with the fast ventricular rate on the background of LBBB.

Background: While patient performance after participating in cardiac rehabilitation programmes after acute myocardial infarction is regularly reported through registry and survey data, information on cardiac rehabilitation programme characteristics is less well described.

Aim: The aim of this study was to evaluate Swedish cardiac rehabilitation programme characteristics and adherence to European Guidelines on Cardiovascular Disease Prevention.

Method: Cardiac rehabilitation programme characteristics at all 78 cardiac rehabilitation centres in Sweden in 2016 were surveyed using a web-based questionnaire (100% response rate).

Background: The effect of a weekend compared with a weekday hospital admission on patient outcomes after an acute coronary syndrome is unclear. This study aims to determine whether collectively there is a weekend effect in acute coronary syndrome.

Method: We conducted a systematic review and meta-analysis of cohort studies examining the association between weekend compared to weekday admission at any time of the day and early mortality (in-hospital or 30-day).

Italy comprises a high proportion of people who never exercised. Low physical activity levels in adolescents is a risk factor for several disorders. The aim of this cohort epidemiological study was to compare physical fitness profiles between boys and girls with regard to age and gender and to identify health and fitness-related markers that contribute to the make-up of Southern Italian teenagers.

Background: Studies have shown variation in care for patients with non-ST elevation myocardial infarction (NSTEMI), including in the roles of specialist and advanced practice nurses in diagnosis, treatment and coordination of care.

Aim: The aim of this study was to describe the roles and responsibilities of specialist and advanced practice nurses in providing care for patients with NSTEMI.

Methods: Secondary analysis of observational field notes and interviews from an ethnographic study of variation in care for NSTEMI patients in 10 UK hospitals conducted 2011-2012.

Background: We aim to determine the prevalence of anemia in acute coronary syndrome (ACS) patients and compare their clinical characteristics, management, and clinical outcomes to those without anemia in an unselected national ACS cohort.

Methods And Results: The Myocardial Ischemia National Audit Project (MINAP) registry collects data on all adults admitted to hospital trusts in England and Wales with diagnosis of an ACS. We conducted a retrospective cohort study by analyzing patients in this registry between January 2006 and December 2010 and followed them up until August 2011.

Background: Incidentally elevated cardiac troponin I (cTnI) levels are common in acutely unwell older patients. However, little is known about how this impacts on the prognosis of these patients.

Objective: We aimed to investigate whether incidentally elevated cTnI levels (group 1) are associated with poorer outcome when compared to age- and sex-matched patients without an elevated cTnI level (group 2), and to patients diagnosed with acute coronary syndrome (group 3).

Objective: This study aims to study the prognostic impact of left ventricular function on mortality and examine the effect of age on the prognostic value of left ventricular function.

Methods: We examined the myocardial ischaemia national audit project registry (2006-2010) data with a mean follow-up of 2.1 years.

Background: observational studies suggest that older patients are less likely to receive secondary prevention medicines following acute coronary syndrome (ACS).

Objectives: to examine the association of increasing age with receipt of specialist care and influence of specialist care on long-term mortality in patients with non-ST elevation myocardial infarction (NSTEMI).

Design: a cohort study.

Hypercholesterolemia is common in older adults and less treated, but little is known about correlates of untreated hypercholesterolemia. Using a standard interview method we examined a random sample of 7,572 participants aged ≥60 years in a community-based household survey across 7 provinces of China during 2007-2012, and documented 328 cases of hypercholesterolemia from self-reported doctor diagnosis. Compared to participants with normal cholesterol, older adults with hypercholesterolemia had higher socioeconomic position and larger body mass index.

Aims: Silent myocardial ischaemia occurs commonly in diabetes. Whether altered perception of ischaemia also predisposes to atypical presentations with under-diagnosis of coronary disease is not known. To determine whether (i) patients with diabetes diagnosed with angina are more likely to report atypical symptoms compared with patients without diabetes, and (ii) atypical symptoms in patients with diabetes cause angina to go unrecognized, increasing the risk of coronary events.

Objective: This study aims to determine whether the prognostic significance of troponins in acute coronary syndrome in predicting mortality varies by age, and if so, to what extent when other prognostic indicators are considered.

Methods: We analysed Myocardial Ischemia National Audit Project registry data collected between January 2006 and December 2010 and followed up this cohort for all-cause mortality until August 2011. Relationships between peak troponin levels (types I and T) and time to death in different age groups, and between age and time to death at different troponin levels were investigated using multiple variable adjusted Cox regression models.

Aims: Older people increasingly constitute a large proportion of the acute coronary syndrome (ACS) population. We examined the relationship of age with receipt of more intensive management and secondary prevention medicine. Then, the comparative association of intensive management (reperfusion/angiography) over a conservative strategy on time to death was investigated by age.

Background And Purpose: Anti-inflammatory cytokine and its genetic variations may play an important role in the process of atherosclerosis. We assessed whether serum interleukin-10 (IL-10) and its genetic variations are associated with ischemic stroke in a Chinese general population.

Methods: An epidemiological survey on cardiovascular diseases and their risk factors was carried in a general population in Beijing in 2005.

Objective: To determine whether the effect of South Asian ethnicity differs between studies of incidence and prognosis of coronary disease.

Design: Systematic literature review and meta-analysis, and cohort analysis from a national acute coronary syndrome (ACS) registry linked to mortality (National Institute of Cardiovascular Outcomes Research/Myocardial Infarction National Audit Project).

Setting: International for the review, and England and Wales for the cohort analysis.
