Ischaemic heart disease

Apical hypertrophic cardiomyopathy (ApHCM) is an HCM variant, affecting frequently males in midlife. It is characterized by apical obliteration and persistent diastolic contraction, often resulting in microvascular ischaemia. We report five cases of ApHCM, with evidence of intramyocardial calcification on echocardiogram. On cardiac magnetic imaging (MRI), a hypointense component at early gadolinium enhancement (EGE) sequences, compatible with calcium, and a deep layer, with hyperintensity at late gadolinium enhancement (LGE) sequences, referable to fibrosis, suggest an endomyocardial fibrosis (EMF) diagnosis...

AIMS: Acute heart failure (AHF) can result in worsening of heart failure (WHF), cardiogenic shock (CS), or death. Risk factors for these adverse outcomes are not well characterized. This study aimed to identify predictors for WHF or new-onset CS in patients hospitalized for AHF. METHODS AND RESULTS: Prospective cohort study enrolling consecutive patients with AHF admitted to a large tertiary care centre with follow-up until death or discharge. WHF was defined by the RELAX-AHF-2 criteria...

BACKGROUND: Loop diuretics are commonly prescribed in the community, not always to patients with a recorded diagnosis of heart failure (HF). The rate of HF events in patients prescribed loop diuretics without a diagnosis of HF is unknown. METHODS: This was a propensity-matched cohort study using data from the Clinical Practice Research Datalink, Hospital Episode Statistics and Office of National Statistics in the UK. Patients prescribed a loop diuretic without a diagnosis of HF (loop diuretic group) between 1 January 2010 and 31 December 2015 were compared with patients with HF (HF group)-analysis A, and patients with risk factors for HF (either ischaemic heart disease, or diabetes and hypertension-at-risk group)-analysis B...

INTRODUCTION: Nigeria is committed to reducing industrial trans- fatty acids (iTFA) from the food supply, but the potential health gains, costs and cost-effectiveness are unknown. METHODS: The effect on ischaemic heart disease (IHD) burden, costs and cost-effectiveness of a mandatory iTFA limit (≤2% of all fats) for foods in Nigeria were estimated using Markov cohort models. Data on demographics, IHD epidemiology and trans- fatty acid intake were derived from the 2019 Global Burden of Disease Study...

BACKGROUND: Prurigo nodularis (PN) presents with intensely itchy hard nodules. Despite being limited to the skin, PN was noted to be associated with systemic diseases including diabetes and chronic renal failure. In previous smaller retrospective studies, several cardiac and vascular diseases were found more frequently in patients with PN. However, small cohort sizes, partially discrepant outcomes, missing data, and incomplete risk assessment limit these findings. METHODS: Electronic health records (EHR)s of 64,801 patients (59...

Diabetes mellitus is a significant risk factor for both ischaemic and haemorrhagic stroke, affecting up to a third of individuals with cerebrovascular diseases. Beyond being a risk factor for stroke, diabetes and hyperglycaemia have a negative impact on outcomes after ischaemic and haemorrhagic stroke. Hyperglycaemia during the acute ischaemic stroke phase is associated with a higher risk of haemorrhagic transformation and poor functional outcome, with evidence in favour of early intervention to limit and manage severe hyperglycaemia...

This study aimed to estimate the association between single dietary risk factors and cardiovascular diseases (CVDs) in the WHO European Region (WHO ER) by age and sex using the data of the Global Burden of Diseases Study (GBD) from 1990 to 2019. For this purpose, 13 dietary risks and 13 forms of CVDs were included in the study, and the comparative risk assessment framework of the GBD was used to estimate the deaths attributable to them. The study included four regions, with a total of 54 countries. In 2019, 1...

BACKGROUND: Improved coronary physiological function after percutaneous coronary intervention (PCI) has been shown to improve prognosis in stable ischaemic heart disease, but has not yet been explored in ST-segment elevated myocardial infarction (STEMI). The study sought to determine whether an improvement in the quantitative flow ratio (QFR) could improve the prognosis of STEMI patients undergoing primary PCI. METHODS: Patients diagnosed with STEMI who were receiving primary PCI were recruited for the study...

Introduction The contribution of medication harm to rehospitalisation and adverse patient outcomes after an acute myocardial infarction (AMI) needs exploration. Rehospitalisation is costly to both patients and the healthcare facility. Following an AMI, patients are at risk of medication harm as they are often older, have multiple comorbidities and polypharmacy. This study aimed to quantify and evaluate medication harm causing unplanned rehospitalisation after an AMI. Methods This was a retrospective cohort study of patients discharged from a quaternary hospital post-AMI...

Infection contributes to developing cardiac arrhythmias, such as atrial fibrillation (AF), which causes over 25% of ischaemic stroke. We analysed a hospital coding database of patients hospitalised with Coronavirus 2019 (COVID-19) ± AF or a lower respiratory tract infection (LRTI) ± AF, to compare the incidence of first-diagnosed or 'new' AF (nAF) between COVID-19 and LRTI, as well as risk factors associated with developing nAF during COVID-19. In total, 2,243 patients with LRTI and 488 patients with COVID-19 were included...

Obesity and chronic kidney disease (CKD) are common and frequently coexisting medical conditions. Already well known to be a risk factor for type 2 diabetes mellitus (T2DM), ischaemic heart disease, stroke, hypertension, malignancy and premature death, obesity also predisposes to CKD. Elevated weight leads to declining renal function through several mechanisms, including established pathways via metabolic syndrome, hypertension and T2DM, but also through relatively recently understood glomerulosclerosis, directly related to obesity...

BACKGROUND: Microplastic (MP) pollution has emerged as a significant environmental concern worldwide. While extensive research has focused on their presence in marine organisms and ecosystems, their potential impact on human health, particularly on the circulatory system, remains understudied. This project aimed to identify and quantify the mass concentrations, polymer types, and physical properties of MPs in human thrombi surgically retrieved from both arterial and venous systems at three anatomically distinct sites, namely, cerebral arteries in the brain, coronary arteries in the heart, and deep veins in the lower extremities...

OBJECTIVES: Compare the risk of extended major adverse cardiovascular (CV) event (MACE) composite outcomes and component events in patients with rheumatoid arthritis (RA) treated with tofacitinib versus tumour necrosis factor inhibitors (TNFi) in Oral Rheumatoid Arthritis Trial (ORAL) Surveillance. METHODS: Patients with RA aged ≥50 years and with ≥1 additional CV risk factor received tofacitinib 5 mg or 10 mg two times per day or TNFi...

AIM: To assess cause-specific death in patients with heart failure with preserved, mildly reduced, and reduced ejection fraction (HFpEF, HFmrEF, and HFrEF). METHODS AND RESULTS: Data were analysed from the Swedish Heart Failure Registry (SwedeHF) and the National Patient Register of patients enrolled in SwedeHF 2000-2021. Cox proportional hazards regression models were performed and adjusted for age, sex and time period. Among 100 584 patients (23% HFpEF, 23% HFmrEF, 53% HFrEF), median age (interquartile range) was 75 (66-82) and 36% were female...

AIMS: Data on Glycoprotein IIb/IIIa inhibitors (GPI) use in real world ACS patients following the introduction of potent P2Y12 inhibitors and newer generation stents are scant. Here, we aimed to assess the utilization, effectiveness, and safety of GPI in a large prospective multi-centre cohort of contemporary ACS patients. METHODS AND RESULTS: SPUM-ACS prospectively recruited patients presenting with ACS between 2009 and 2017. The primary endpoint of the present study was major adverse cardiovascular events (MACE), a composite of all-cause death, non-fatal myocardial infarction (MI) and non-fatal stroke at one year...

BACKGROUND: The coronary sinus reducer (CSR) is proposed to reduce angina in patients with stable coronary artery disease by improving myocardial perfusion. We aimed to measure its efficacy, compared with placebo, on myocardial ischaemia reduction and symptom improvement. METHODS: ORBITA-COSMIC was a double-blind, randomised, placebo-controlled trial conducted at six UK hospitals. Patients aged 18 years or older with angina, stable coronary artery disease, ischaemia, and no further options for treatment were eligible...

Stable angina, one manifestation of chronic coronary syndrome (CCS), is characterised by intermittent episodes of insufficient blood supply to the myocardium, provoking symptoms of myocardial ischaemia, particularly chest pain. These attacks usually occur during exercise or stress. Anti-ischaemic drugs are the mainstay of pharmacologic management of CCS with symptoms of angina. β-blockers reduce heart rate and myocardial contractility, thus reducing myocardial oxygen consumption. These drugs have been shown to ameliorate the frequency of anginal attacks and to improve exercise capacity in these patients...

BACKGROUND: Ageing populations are increasing the demand for knee arthroplasty. Concurrently, the prevalence of medical comorbidities are rising too. The Self-Administered Comorbidity Questionnaire was developed to provide a patient's assessment of their own comorbidities whereas the American Society of Anesthesiologists grades and the Charlson Comorbidity Index utilise clinical evaluation to objectively measure perioperative morbidity and mortality risk. The primary aim of this study was to compare Self-Administered Comorbidity Questionnaire scores with American Society of Anesthesiologists grades and Charlson Comorbidity Index scores...

BACKGROUND AND OBJECTIVES: Atherosclerotic renal artery stenosis may cause hypertension, chronic kidney disease and heart failure, but large randomized control trials to date have shown no major additional benefit of renal revascularization over optimal medical management. However, these trials did not consider outcomes specifically in relation to clinical presentations. Given that atherosclerotic renal artery stenosis is a heterogenous condition, measures of success likely differ according to the clinical presentation...
