Myocardial Infarction with Non-Obstructed Coronary Arteries (MINOCA) is common, but the causes are to a large extent unknown. Thus, we aimed to study the prevalence of myocarditis and "true" myocardial infarction determined by cardiac magnetic resonance (CMR) imaging in MINOCA patients, and risk markers for these two conditions in this population. ⋯ The results of this meta-analysis of individual data showed that myocarditis and "true" myocardial infarction are common in MINOCA when determined by CMR imaging. This information emphasizes the importance of performing CMR imaging in MINOCA patients and can be used clinically to guide diagnostics and treatment of MINOCA patients.

Review Meta Analysis
Breast arterial calcifications: a systematic review and meta-analysis of their determinants and their association with cardiovascular events.
Breast arterial calcifications (BAC), regularly observed at mammography, are medial calcifications and as such an expression of arteriosclerosis. Our objective was to evaluate and summarize the available evidence on the associations of BAC with cardiovascular risk factors and cardiovascular risk. ⋯ BAC appear to be associated with an increased risk of cardiovascular disease events, while only being associated with some of the known cardiovascular risk factors, illustrating that medial arterial calcification might contribute to cardiovascular disease through a pathway distinct from the intimal atherosclerotic process.

Review Meta Analysis
Effect of continuous positive airway pressure on lipid profile in patients with obstructive sleep apnea syndrome: a meta-analysis of randomized controlled trials.
Obstructive sleep apnea syndrome (OSAS) is an independent risk factor for development of dyslipidemia. Continuous positive airway pressure (CPAP) is the first-line treatment for OSAS. However, it is unclear whether CPAP improves lipid metabolism. ⋯ We confirmed that CPAP decreases the TC level, especially in OSAS patients who are younger, more obese, and who use CPAP for a longer period. CPAP did not alter TG, LDL, or HDL levels, suggesting that CPAP may have no clinically important effect on lipid metabolism.

Sugar sweetened beverages consumption and risk of coronary heart disease: a meta-analysis of prospective studies.
To summarize the evidence with respect to sugar sweetened beverages (SSBs) consumption and risk of coronary heart disease (CHD) and to recommend field standards for future analysis on this topic. ⋯ Our meta-analysis of four studies suggests that consumption of SSBs may increase risk of CHD, especially among men and American populations. However, this finding was based on limited studies; further studies are warranted to critically evaluate the relationship.

Review Meta Analysis Comparative Study
Impact of new oral or intravenous P2Y12 inhibitors and clopidogrel on major ischemic and bleeding events in patients with coronary artery disease: a meta-analysis of randomized trials.
New P2Y12 inhibitors can be classified as oral (prasugrel and ticagrelor) and intravenous drugs (cangrelor and elinogrel). These P2Y12 inhibitors might be superior to clopidogrel for reducing ischemic events in patients with coronary artery disease (CAD). We performed a meta-analysis of randomized trials that compared new oral or intravenous P2Y12 inhibitors with clopidogrel to determine their efficacy and safety in patients. ⋯ New oral P2Y12 inhibitors reduce ischemic events, but there is no obvious increase in major bleeding in patients with CAD, and the risk/benefit ratio is particularly favorable for STEMI patients. Moreover, only cangrelor is beneficial for ischemic events in patients on new intravenous P2Y12 inhibitors.
