The Reduction of Mortality in Acute Myocardial Infarction: From Bed Rest to Future Directions.

Despite the reduction of mortality secondary to cardiovascular diseases observed in the last decades, ischemic heart disease remains the most common cause of death worldwide. Among the spectrum of ischemic heart disease, myocardial infarction accounts for most deaths. Since the introduction of the coronary care units in the 1960s, and until the latest antithrombotic drugs, myocardial infarction survival improved by 40-50%.

Long-Term Contrast Echocardiography and Clinical Follow-Up after Percutaneous Closure of Patent Foramen Ovale Using Two Different Atrial Septal Occluder Devices.

Introduction: Percutaneous patent foramen ovale (PFO) closure by means of a septal occluder device (SOD) is a well-known therapeutic strategy for the secondary prevention of paradoxical embolic neurological events. The aim of this study was to provide long-term echocardiographic and clinical follow-up data on patients who had undergone percutaneous PFO closure with 2 different SOD.

Methods: We selected 2 groups of patients treated with 2 different SOD: Group A: 52 patients with an Amplatzer(®) PFO Occluder and Group B: 49 patients with a Figulla Flex(®) device.

Asymmetric and Symmetric Dimethylarginine and Sympathetic Nerve Traffic after Renal Denervation in Patients with Resistant Hypertension.

Background And Objectives: The plasma concentration of the endogenous inhibitor of nitric oxide synthase asymmetric dimethylarginine (ADMA) associates with sympathetic activity in patients with CKD, but the driver of this association is unknown.

Design, Setting, Participants, & Measurements: In this longitudinal study (follow-up: 2 weeks-6 months), repeated measurements over time of muscle sympathetic nerve activity corrected (MSNAC), plasma levels of ADMA and symmetric dimethylarginine (SDMA), and BP and heart rate were performed in 14 patients with drug-resistant hypertension who underwent bilateral renal denervation (enrolled in 2013 and followed-up until February 2014). Stability of ADMA, SDMA, BP, and MSNAC over time (6 months) was assessed in two historical control groups of patients maintained on stable antihypertensive treatment.

Automated carbon dioxide digital angiography for lower-limb arterial disease evaluation: safety assessment and comparison with standard iodinated contrast media angiography.

Introduction: Carbon dioxide (CO2) has been validated as a contrast agent in a large series of studies. A particular advantages of CO2 over iodinated contrast medium (ICM) is the absence of nephrotoxicity and allergic reactions. One of the limitations of CO2 angiography is the difficulty of CO2 manual injection due to its compressibility.
