REVIEW
Saeid Kargozar, Sepideh Hamzehlou, Francesco Baino
Repair and regeneration of disorders affecting cardiac and pulmonary tissues through tissue-engineering-based approaches is currently of particular interest. On this matter, different families of bioactive glasses (BGs) have recently been given much consideration with respect to treating refractory diseases of these tissues, such as myocardial infarction. The inherent properties of BGs, including their ability to bond to hard and soft tissues, to stimulate angiogenesis, and to elicit antimicrobial effects, along with their excellent biocompatibility, support these newly proposed strategies...

Magnetic resonance rotating frame relaxation times are an alternative non-contrast agent choice for the diagnosis of chronic myocardial infarct. Fibrosis typically occurs in progressive hypertrophic cardiomyopathy. Fibrosis has been imaged in myocardial infarcted tissue using rotating frame relaxation times, which provides the possibility to follow up progressive cardiomyopathy without contrast agents. Mild and severe left ventricular hypertrophy were induced in mice by transverse aortic constriction, and the longitudinal rotating frame relaxation times (T1ρ ) and relaxation along the fictitious field (TRAFF2 , TRAFF3 ) were measured at 5, 10, 24, 62 and 89 days after transverse aortic constriction in vivo...

BACKGROUND: Atypical clinical presentation in acute myocardial infarction (AMI) patients is not uncommon; most studies suggest that it is associated with unfavorable prognosis. HYPOTHESIS: Long-term clinical impact differs according to predominant symptom presentation (typical chest pain, atypical chest pain, syncope, cardiac arrest, or dyspnea) in AMI patients. METHODS: FAST-MI 2010, a nationwide French registry, included 4169 patients with AMI in 213 centers at the end of 2010 (76% of active centers)...

Exosomes are required for the regenerative effects of human cardiosphere-derived cells (CDCs). Studies show that they mimic the cardioprotective benefits of CDCs in rodents and porcine myocardial infarction (MI) models. Hypoxic preconditioning of stem cells increases the cardioprotective effects of exosomes in MI models by enhancing angiogenesis. Several exosomal microRNAs (miRNAs) up-regulate in response to hypoxia and play a role in cardioprotective and pro-angiogenic effects. In this study, we have demonstrated that human CDCs secreted exosomes under hypoxic conditions (1% O2 for 2 days) enhanced tube formation by human umbilical vein endothelial cells (HUVECs) at a concentration of 25 μg/ml...

Background Myocardial infarction-triggered acute stress disorder (ASD) and subclinical inflammation associate with the development of posttraumatic stress disorder, and worsen the prognosis of myocardial infarction patients. We examined the relationship between ASD severity and C-reactive protein levels in patients with acute myocardial infarction. Methods We assessed 190 patients (median age 59 years; 83% men) with a verified myocardial infarction within 48 h of an acute coronary intervention. Circulating levels of C-reactive protein were categorized according to their prognostic risk for cardiovascular disease: 0 to <5, 5 to <10, 10 to <20, and ≥ 20 mg/l...

OBJECTIVES: This study sought to examine the relationship between temperature at reperfusion and infarct size. BACKGROUND: Hypothermia consistently reduces infarct size when administered prior to reperfusion in animal studies, however, clinical results have been inconsistent. METHODS: We performed a patient-level pooled analysis from six randomized control trials of endovascular cooling during primary percutaneous coronary intervention (PCI) for ST-segment elevation myocardial infarction (STEMI) in 629 patients in which infarct size was assessed within 1 month after randomization by either single-photon emission computed tomography (SPECT) or cardiac magnetic resonance imaging (cMR)...

BACKGROUND: Excessive daytime sleepiness is a frequent symptom of obstructive sleep apnea (OSA) and has been proposed as a motivator for adherence to continuous positive airway pressure (CPAP) therapy. However, excessive daytime sleepiness is absent in many patients with coronary artery disease (CAD) and concomitant OSA. We evaluated long-term use of CPAP and predictors of CPAP use in nonsleepy and sleepy OSA patients from a CAD cohort. HYPOTHESIS: Long-term CPAP use is lower in CAD patients with nonsleepy OSA vs sleepy OSA...

Myocardial infarction leads to an irreversible loss of vital myocardial cells. The transplantation of new cardiomyocytes into the heart was first described over 20 years ago and represents a straightforward approach to remuscularize a damaged heart. Due to the lack of human cells a clinical application seemed ambitious; however, dramatic progress in stem cell biology over the last two decades has paved the way towards a clinical application. This is especially important as the prognosis for patients with terminal heart failure is still poor...

Left ventricular end-diastolic pressure (LVEDP) is an easily obtained, physiologically integrative measure of total LV function. LVEDP may be a useful prognostic measure in patients with acute myocardial infarction and utilised to guide medical therapy and assess risk for post myocardial infarction heart failure. To assess the utility of LVEDP as a prognostic measure in patients presenting with acute myocardial infarction. We performed an unrestricted search of electronic databases (1946 to March 2017) using a predefined search strategy...

Conditioning-like infarct limitation by enhanced level of hydrogen sulfide (H2S) has been demonstrated in many animal models of myocardial ischemia/reperfusion injury (MIRI) in vivo. We sought to evaluate the effect of H2S on myocardial infarction across in vivo pre-clinical studies of MIRI using a comprehensive systematic review followed by meta-analysis. Embase, Pubmed and Web of Science were searched for pre-clinical investigation of the effect of H2S on MIRI in vivo. Retained records (6031) were subjected to our pre-defined inclusion criteria then were objectively critiqued...
