L&#39;angioplastica primaria, l&#39;intervallo tra il primo contatto medico (FMC) e riperfusione dovrebbe essere meno di 120 minuti. Il tempo di riperfusione varia a seconda di dove &egrave; stabilito FMC. Studi recenti suggeriscono pi&ugrave; volte in pazienti che presentano in fuori orario. L&#39;obiettivo &egrave; quello di valutare gli intervalli di tempo tra l&#39;insorgenza dei sintomi e riperfusione secondo cui si verifica il FMC e il momento della giornata di presentazione paziente.

In prim&auml;re Angioplastie sollte das Intervall zwischen &auml;rztlichen Erstkontakt (FMC) und Reperfusion weniger als 120 Minuten. Die Zeit zur Reperfusion h&auml;ngt von dem FMC ans&auml;ssig ist. Neuere Studien legen nahe, l&auml;ngere Zeiten bei Patienten, die in Ruhezeiten zu pr&auml;sentieren. Ziel ist es, die Zeitintervalle zwischen dem Auftreten von Symptomen und Reperfusion nach wo die FMC auftritt und Zeit des Tages Patienten Pr&auml;sentation zu bewerten.

In primary angioplasty, the interval between first medical contact (FMC) and reperfusion should be less than 120 minutes. The time to reperfusion varies depending on where FMC is established. Recent studies suggest longer times in patients presenting in off-hours. The objective is to evaluate the time intervals between the onset of symptoms and reperfusion according to where the FMC occurs and time of day of patient presentation.

Use of the transradial approach (TRA) in percutaneous coronary intervention (PCI) has increased in recent years. TRA has a lower mortality rate than the transfemoral approach (TFA) in patients with acute coronary syndrome. Comparative studies have systematically excluded patients with cardiogenic shock (CS).

Integration of a local into a regional primary angioplasty action plan (the Catalan Codi Infart network) reduces time to reperfusion.

Previous trials in elderly patients with ST-elevation myocardial infarction (STEMI) have not shown a definitive benefit of primary percutaneous coronary intervention (PPCI) by transfemoral approach over thrombolysis. The transradial approach (TRA) is associated with a significant decrease in mortality, MACE (Major Adverse Cardiac Event), and serious access site complications compared with the transfemoral approach. We have evaluated clinical outcomes in a cohort of real-life unselected ≥75-year-old patients with STEMI treated by TRA-PPCI. This is a single-center prospective, observational registry of consecutive patients with STEMI who underwent PPCI between February 2007 and February 2013. MACE was defined as death, reinfarction, or stroke. A total of 307 patients were treated by PPCI, 293 (95.1%) with TRA-PPCI (mean age 80 ± 2 years, 42% women). Patients had high co-morbidity levels (cardiogenic shock on admission 8.5%, previous myocardial infarction 11.6%, diabetes 30.4%, previous renal failure 25.6%, previous PCI 9.6%, and peripheral arterial disease 14.3%); IIbIIIa inhibitors were used in 45.1% of patients. Severe bleeding and need for transfusion were recorded for 6.5% and 9.9% of patients, respectively. In-hospital mortality, 1-year mortality, and 1-year MACE were 11.9%, 17.4%, and 22.2%, respectively. Excluding 25 patients with cardiogenic shock on admission, the in-hospital mortality, 1-year mortality, and 1-year MACE were 7.8%, 13.1%, and 17.9%, respectively. In conclusion, TRA-PPCI was feasible in the vast majority of elderly patients with STEMI. In-hospital mortality, 1-year mortality, and 1-year MACE were lower than reported for transfemoral access, suggesting a benefit of the TRA in these patients.

Renal denervation is a percutaneous intervention for the treatment of resistant hypertension. Randomized studies have shown contradictory results on its efficacy. We present the results of a renal denervation registry for the treatment of resistant hypertension in real-life patients in Spain.

There is an increasing need for safe and simple techniques for sensing devices and prostheses implanted inside the human body. Microwave wireless inspection may be an appropriate technique for it. The implanted device may have specific characteristics that allow to distinguish it from its environment. A new sensing technique based on the principle of differential resonance is proposed and its basic parameters are discussed. This technique allows to use the implant as a signal scattering device and to detect changes produced in the implant based on the corresponding change in its scattering signature. The technique is first tested with a canonic human phantom and then applied to a real in vivo clinical experiment to detect coronary stents implanted in swine animals.

The COVID-19 outbreak has had an unclear impact on the treatment and outcomes of patients with ST-segment elevation myocardial infarction (STEMI). The aim of this study was to assess changes in STEMI management during the COVID-19 outbreak.
