Background: Stroke mimics are non-vascular conditions that present with acute focal neurological deficits, simulating an acute ischemic stroke. Susumber berry (SB) toxicity is a rare cause of stroke mimic with limited case reports available in the literature.

Objectives: We report four new cases of SB toxicity presenting as stroke mimic, and we performed a systematic review.

Background And Purpose: Skeletal muscle symptoms and elevated creatine kinase (CK) levels have been consistently reported as part of the COVID-19 disease process. Previous studies have yet to show a consistent relationship between CK levels and skeletal muscle symptoms, disease severity, and death from COVID-19. The purpose of this study is to determine whether elevated CK is associated with a COVID-19 course requiring intubation, intensive care, and/or causing death.

Background: To compare clinical and psychological factors among patients with self-perceived statin-associated muscle symptoms (SAMS), confirmed SAMS, and refuted SAMS in coronary heart disease patients (CHD).

Methods: Data were obtained from a cross-sectional study of 1100 CHD outpatients and a study of 71 CHD outpatients attending a randomized, double-blinded, placebo-controlled, crossover study to test effects of atorvastatin 40 mg/day on muscle symptom intensity. Clinical and psychosocial factors were compared between patients with and without SAMS in the cross-sectional study, and between patients with confirmed SAMS and refuted SAMS in the randomized study.

Background And Aims: We aimed to determine the relationship between statin adherence measured directly, and by self-report measures and serum cholesterol levels.

Methods: Patients prescribed atorvastatin (N = 373) participated in a cross-sectional study 2-36 months after a coronary event. Self-reported adherence included statin adherence the past week, the 8-item Morisky medication adherence scale (MMAS-8), and the Gehi et al.

Cardiovascular disease is a model example of a preventable condition for which practice guidelines are particularly important. In 2016, the joint task force created by the European Society of Cardiology (ESC) together with 10 other societies released the new version of the European guidelines on cardiovascular disease prevention. To facilitate the implementation of the ESC guidelines, a dedicated prevention implementation committee has been established within the European Association of Preventive Cardiology.

To determine longitudinal changes in lifestyle behaviour and lipid management in a chronic coronary heart disease (CHD) population. A multi-centre cohort study consecutively included 1127 patients at baseline in 2014-2015, on average 16 months after a CHD event. Data were collected from hospital records, a questionnaire and clinical examination.

Aims: To estimate the effect of atorvastatin on muscle symptom intensity in coronary heart disease (CHD) patients with self-perceived statin-associated muscle symptoms (SAMS) and to determine the relationship to blood levels of atorvastatin and/or metabolites.

Methods And Results: A randomized multi-centre trial consecutively identified 982 patients with previous or ongoing atorvastatin treatment after a CHD event. Of these, 97 (9.

Background: The relative importance of lifestyle, medical and psychosocial factors on the risk of recurrent major cardiovascular (CV) events (MACE) in coronary patients' needs to be identified. The main objective of this study is to estimate the association between potentially preventable factors on MACE in an outpatient coronary population from routine clinical practice.

Methods: This prospective follow-up study of recurrent MACE, determine the predictive impact of risk factors and a wide range of relevant co-factors recorded at baseline.

Purpose: The reasons why many coronary patients are inactive or have a low level of physical activity (PA) are not completely understood. We identified medical and psychosocial factors associated with PA status and increasing exercise level after a coronary event.

Methods: A cross-sectional study investigated the factors associated with PA in 1101 patients hospitalized with myocardial infarction (MI) and/or a revascularization procedure.

Background: Understanding the determinants associated with prediabetes and type 2 diabetes in coronary patients may help to individualize treatment and modelling interventions. We sought to identify sociodemographic, medical and psychosocial factors associated with normal blood glucose (HbA1c < 5.7%), prediabetes (HbA1c 5.

Background: Reports are conflicting on whether serum uric acid (sUA) levels are independently associated with increased cardiovascular (CV) death risk.

Methods: This post hoc analysis assessed the relationship between sUA levels and CV death risk score in 7531 patients from the cross-sectional, multinational EURIKA study (NCT00882336). Patients had at least one CV risk factor but no clinical CV disease.

We identified sociodemographic, medical, and psychosocial factors associated with unfavorable blood pressure (BP) control in 1012 patients, hospitalized with myocardial infarction and/or a coronary revascularization procedure. This cross-sectional study collected data from hospital records, a comprehensive self-report questionnaire, clinical examination, and blood samples after 2-36 (mean 17) months follow-up. Forty-six percent had unfavorable BP control (≥140/90 [80 in diabetics] mm Hg) at follow-up.
