Platypnea-orthodeoxia syndrome is an intriguing condition that comprehends multiple pathologic phenomena. It requires a high clinical suspicion and is probably underdiagnosed. ⋯ We propose that a separate entity is created within the spectrum of platypnea-orthodeoxia syndrome that is responsible for the majority of cases, namely platypnea-orthodeoxia disease, which would be defined as the existence of an interatrial communication, with a right-to-left shunt, normal pressure in the right atrium and, of course, platypnea and orthodeoxia. Most patients with this disease were submitted to percutaneous closure of the patent foramen ovale or atrial septal defect, with favorable results, making it the first-line therapeutic approach nowadays.

Randomized Controlled Trial
Beneficial effects of high-dose atorvastatin pretreatment on renal function in patients with acute ST-segment elevation myocardial infarction undergoing emergency percutaneous coronary intervention.
To investigate whether preprocedural high-dose atorvastatin decreases the incidence of contrast-induced nephropathy (CIN) and protects the renal function after emergency percutaneous coronary intervention (PCI). ⋯ Preprocedural high-dose atorvastatin prevents CIN and protects the renal function in patients with acute STEMI undergoing emergency PCI.

We aimed to test the hypothesis that hemoglobin values add prognostic information to the Global Registry of Acute Coronary Events (GRACE) score at admission in patients with non-ST elevation acute coronary syndromes (ACS). ⋯ The present study provides preliminary evidence that hemoglobin level independently predicts recurrent events during hospitalization and improves the prognostic performance of the GRACE score in patients with non-ST elevation ACS.

To determine the risk of short- and long-term mortality and major adverse cardiac events (MACE) in acute myocardial infarction (AMI) patients complicated by cardiogenic shock (CS) in the contemporary practice of primary percutaneous coronary intervention with stenting. ⋯ CS complicating AMI is still a severe clinical event, mainly with regard to a significant higher risk of early mortality, but also associated with a worse prognosis in 30-day survivors.

Therapeutic hypothermia is currently used to reduce neurological ischemic damage in postcardiac arrest patients. Nevertheless, it has been associated with relevant side effects such as infections, bleeding, hypotension and hyperkalemia. Although hypothermia-induced coronary spasm is rare, its occurrence needs to be considered attentively as it adds a high risk of ventricular arrhythmias and cardiac arrest in patients with already-existing critical heart conditions.
