Case Reports[True posterior infarction diagnosis. Report of three cases].
Acute Coronary Syndrome with ST segment elevation requires rapid reperfusion, which is why the timely identification of these conditions, based on the patient's symptoms and the correct interpretation of the EKG, is essential for therapeutic decisions. We report three patients with True Posterior Infarction and their difficult EKG diagnosis. The classic 12-lead EKG method is often not capable of supporting the diagnosis, so we recommend the use of posterior leads and mirror images observing inverted V1-V2-V3 leads on the classic EKG.

[Association between cardiometabolic risk and cognitive impairment].
Several risk factors are associated with cognitive impairment in older people, but little attention has been paid to cardiometabolic variables, as well as how cognitive reserve can mediate this association. ⋯ A direct effect of cardiometabolic risk factors on cognitive functioning was observed.

Chemical composition analysis of urinary stones is a fundamental part of the metabolic workup of urolithiasis. ⋯ These findings do not differ from those found in developed countries.

Cervicocranial arterial dissection (CIAD) is an important cause of stroke. ⋯ Due to the greater availability of non-invasive imaging methods, 50% of these patients with CIAD did not have a stroke. Thus, an earlier and more timely management is feasible.

[Coronary artery bypass grafting or percutaneous coronary intervention in patients with severe three vessel disease].
Recent randomized controlled trials confirmed the beneficial outcomes with coronary artery bypass grafting (CABG) compared with percutaneous coronary intervention (PCI) in patients with severe three-vessel coronary artery and left main disease. An increased long-term survival after CABG is associated with a reduction in spontaneous myocardial infarction and repeat revascularization rates. While PCI treats only flow-limiting lesions, CABG treats the whole coronary artery, preventing events in the future. Due to different clinical and anatomic factors affecting the outcomes, the heart team should formulate treatment assignment recommendations.
