Background: Due to sensorial autonomic neuropathy, the type and severity of angina pectoris in patients with diabetes mellitus (DM) may be rather different from the type and severity of angina pectoris in patients without DM.
Hypothesis: The aim of the study was to understand if angina pectoris is related to extensive coronary artery disease (CAD) in patients with DM.
Methods: The study included 530 patients with DM who underwent coronary angiography at our center in 2009 and 2010. Patients were divided into 4 groups according to type of chest pain: group 1, noncardiac chest pain or no pain; group 2, angina equivalent; group 3, atypical angina; and group 4, typical angina. All angiograms were re-evaluated and Gensini scores were calculated. Three-vessel disease was diagnosed in the presence of stenosis >50% in all 3 coronary artery systems.
Results: There were no statistically significant differences between the groups with regard to age, sex, systolic or diastolic blood pressures, body mass index, creatinine clearance, or lipid profile. Fasting blood glucose was significantly higher in group 4 than in group 2. Gensini scores were not statistically different between groups 1 and 2 or between groups 3 and 4; however, the scores for groups 3 and 4 were higher than the score for either group 1 or group 2. Prevalence of 3-vessel disease was significantly higher in groups 3 and 4 compared with the other groups.
Conclusions: The presence of angina pectoris was related to extensive CAD in patients with DM. The extent of CAD was not correlated with the type of angina (typical or atypical).

A young man presented with complaints of angina on exertion and dyspnoea on exertion for the last 3 months. On evaluation, he was found to have a cystic mass in the left ventricle with severe left ventricular systolic dysfunction. A cardiac MRI revealed a multiloculated mass in the left ventricle with multiple septa with internal enhancement and CT coronary angiography revealed compression of a coronary artery by the cystic mass.

Objective: While chest pain is a common symptom, its prevalence among women and men across ethnic groups is unknown. Moreover, how chest pain is associated with general practitioner (GP) and cardiologist visits in women and men across ethnic groups, remains to be determined.
Design: We used baseline data on 12423 women and 9071 men from the multi-ethnic HELIUS cohort (Amsterdam, the Netherlands; 2011-2015).

Background And Aims: Globally, ischaemic heart disease (IHD) is a leading cause of death among women; however, disparities remain in the diagnosis and treatment of IHD between females and males. There is limited evidence about mortality risks among women with symptoms of IHD who remain undiagnosed. We re-examined the mortality risks in midlife women who completed the Rose Angina Questionnaire, among a subset of the Royal College of General Practitioners' Oral Contraception Study cohort.

Coronary artery disease (CAD) is the leading cause of death worldwide. Acute coronary syndrome (ACS) encompasses a spectrum of diagnoses ranging from unstable angina pectoris to myocardial infarction with and without ST-segment elevation and frequently presents as the first clinical manifestation. It is crucial in this scenario to perform a timely and comprehensive assessment of patients by evaluating the clinical presentation, electrocardiogram and laboratory diagnostics using highly sensitivity cardiac troponin in order to initiate a timely and risk-adapted continuing treatment with immediate or early invasive coronary angiography.

Background: Microvascular angina (MVA) is an important contributor to morbidity and mortality in patients with non-obstructive coronary artery disease. Despite improvements in its recognition and diagnosis, uncertainty remains around the most effective treatment strategy, and more data are needed.
Aims: We aimed to evaluate the quality of patient selection in treatment studies of MVA and provide a contemporary overview of the evidence base for the treatment of MVA.
