Characterization of the Insular Role in Cardiac Function through Intracranial Electrical Stimulation of the Human Insula.

OBJECTIVE: The link between brain function and cardiovascular dynamics is an important issue yet to be elucidated completely. The insula is a neocortical brain area that is thought to have a cardiac chronotropic regulatory function, but its role in cardiac contractility is unknown. We aimed to analyze the variability in heart rate and cardiac contractility after functional activation of different insular regions through direct electrical stimulation (E-stim) in humans. METHODS: This was an observational, prospective study, including patients admitted for stereo-electroencephalographic recording because of refractory epilepsy, in whom the insular cortex was implanted. Patients with anatomical or electrophysiological insular abnormalities and those in whom E-stim produced subjective symptoms were excluded. Variations in heart rate (HR), stroke volume (SV), and cardiac output (CO) were analyzed during insular E-stim and compared with control E-stim of non-eloquent brain regions and sham stimulations. RESULTS: Ten patients were included, 5 implanted in the right insula (52 E-stim) and 5 in the left (37 E-stim). Demographic and clinical characteristics of both groups were similar. E-stim of both right and left insulas induced a significant decrease of the CO and HR, and an increase of the SV. E-stim of control electrodes and sham stimulations were not associated with variations in cardiac function. Blood pressure and respiratory rate remained unaltered. INTERPRETATION: Our results suggest a direct chronotropic and inotropic cardiac depressor function of the right and left insulas. The evidence of an insular direct cardiac regulatory function might open a path in the prevention or treatment of heart failure, arrhythmias, and sudden unexpected death in epilepsy.

Estratificación basal de riesgo en pacientes mayores de 75 años con infarto y shock cardiogénico referidos para angioplastia primaria / Baseline risk stratification of patients older than 75 years with infarction and cardiogenic shock undergoing primary angioplasty

Introducción y objetivos: Los pacientes mayores de 75 años con infarto agudo de miocardio con elevación del segmento ST sometidos a angioplastia primaria en situación de shock cardiogénico sufren una gran mortalidad. La identificación previa al procedimento de variables predictoras de la posterior mortalidad sería muy útil para guiar la toma de decisiones. Métodos: Análisis del registro multicéntrico de angioplastia primaria en pacientes mayores de 75 años (ESTROFA MI+75), que incluye a 3.576 pacientes. Se analizaron las características y la evolución clínica del subgrupo con shock cardiogénico para identificar predictores de supervivencia a 1 año tras la angioplastia y elaborar un índice pronóstico. Se validó el índice en una cohorte independiente. Resultados: Se incluyó a 332 pacientes. Los predictores basales independientes fueron: la localización anterior (HR=2,8; IC95%, 1,4-6,0; p=0,005), una fracción de eyección<40% (HR=2,3; IC95%, 1,14-4,50; p=0,018) y un tiempo entre el inicio de los síntomas y la angioplastia >6 h (HR=3,2; IC95%, 1,6-7,5; p=0,001). Se diseñó un índice basado en estas variables (índice «6-ANT-40»). La supervivencia a 1 año fue del 54,5% de aquellos con índice 0, el 32,3% con índice 1, el 27,4% con índice 2 y el 17% con índice 3 (p=0,004, estadístico C=0,70). En una cohorte independiente de 124 pacientes, las supervivencias a 1 año fueron del 64,5, el 40,0, el 28,9 y el 22,2% respectivamente (p=0,008; estadístico C=0,68). Conclusiones: Un índice basado en simples variables clínicas previas al procedimiento (localización anterior, fracción de eyección<40%, demora >6 h) permite estimar la supervivencia tras una angioplastia primaria de los pacientes mayores con shock cardiogénico, y así ayudar en la toma de decisiones

Background and objectives: Patients older than 75 years with ST-segment elevation myocardial infarction undergoing primary angioplasty in cardiogenic shock have high mortality. Identification of preprocedural predictors of short- and long-term mortality could be useful to guide decision-making and further interventions. Methods: We analyzed a nationwide registry of primary angioplasty in the elderly (ESTROFA MI+75) comprising 3576 patients. The characteristics and outcomes of the subgroup of patients in cardiogenic shock were analyzed to identify associated factors and prognostic predictors in order to derive a baseline risk prediction score for 1-year mortality. The score was validated in an independent cohort. Results: A total of 332 patients were included. Baseline independent predictors of mortality were anterior myocardial infarction (HR 2.8, 95%CI, 1.4-6.0; P=.005), ejection fraction<40% (HR 2.3, 95%CI, 1.14-4.50; P=.018), and time from symptom onset to angioplasty >6hours (HR 3.2, 95%CI, 1.6-7.5; P=.001). A score was designed that included these predictive factors (score "6-ANT-40"). Survival at 1 year was 54.5% for patients with score 0, 32.3% for score 1, 27.4% for score 2 and 17% for score 3 (P=.004, c-statistic 0.70). The score was validated in an independent cohort of 124 patients, showing 1-year survival rates of 64.5%, 40.0%, 28.9%, and 22.2%, respectively (P=.008, c-statistic 0.68). Conclusions: A preprocedural score based on 3 simple clinical variables (anterior location, ejection fraction<40%, and delay time >6 hours) may be used to estimate survival after primary angioplasty in elderly patients with cardiogenic shock and to guide preinterventional decision-making

Multivessel disease in patients over 75years old with ST elevated myocardial infarction. Current management strategies and related clinical outcomes in the ESTROFA MI+75 nation-wide registry.

BACKGROUND: In elderly patients with ST elevated myocardial infarction (STEMI) and multivessel disease (MVD the outcomes related with different revascularization strategies are not well known. METHODS: Subgroup-analysis of a nation-wide registry of primary angioplasty in the elderly (ESTROFA MI+75) with 3576 patients over 75years old from 31 centers. Patients with MVD were analyzed to describe treatment approaches and 2years outcomes. RESULTS: Of 1830 (51%) with MVD, 847 (46%) underwent multivessel revascularization either in acute (51%), staged (44%) or both procedures (5%). Patients with previous myocardial infarction and those receiving drug-eluting stents or IIb-IIIa inhibitors were more prone to be revascularized, whereas older patients, females and those with Killip III-IV, renal failure and higher ejection fraction were less likely. Survival free of cardiac death and infarction at 2years was better for those undergoing multivessel PCI (85.8% vs. 80.4%, p<0.0008), regardless of Killip class. Multivessel PCI was protective of cardiac death and infarction (HR 0.60, 95% CI 0.40-0.89; p=0.011). Complete revascularization made no difference in outcomes among those patients undergoing multivessel PCI. The best prognosis corresponded to those undergoing multivessel PCI in staged procedures (p<0.001). A propensity score matching analysis (514 patients in each group) yielded similar results. CONCLUSIONS: In elderly patients with STEMI and MVD, multivessel PCI was related with better outcomes especially after staged procedures. Among those undergoing multivessel PCI, anatomically defined completeness of revascularization had not prognostic influence. SUMMARY: We sought to investigate the revascularization strategies applied and their prognostic implications in patients aged over 75years with ST elevated myocardial infarction showing multivessel disease. Of 1830 patients, 847 (46%) underwent multivessel PCI either in acute (51%), staged (44%) or both procedures (5%). Multivessel PCI was independent predictor of cardiac death and infarction with the best prognosis corresponding to those undergoing staged procedures.

Early aspirin desensitization in unstable patients with acute coronary syndrome: Short and long-term efficacy and safety.

BACKGROUND: Aspirin hypersensitivity is not a rare condition among patients with acute coronary syndrome. However, despite the publication of several successful desensitization protocols, the procedure is not as widespread as expected. We present a cohort of patients with acute coronary syndrome undergoing aspirin desensitization to evaluate its short- and long-term efficacy and safety and to reinforce data from previous studies. METHODS: Of 1306 patients admitted to our Coronary Care Unit between February 2011 and February 2013, 24 (1.8%) had a history of aspirin hypersensitivity. All 24 patients underwent an eight-dose aspirin desensitization protocol (0.1, 0.3, 1, 3, 10, 25, 50 and 100 mg of aspirin given by mouth every 15 minutes) after premedication with antihistamines and corticosteroids or antileucotrienes. Previously prescribed ß blockers and angiotensin-converting enzyme inhibitors were not discontinued. All patients were desensitized within 72 hours of admission. Those requiring urgent catheterization (five patients with ST segment elevation myocardial infarction) were desensitized within 12 hours of catheterization and the remainder before catheterization. RESULTS: All patients were successfully desensitized and only one presented with an urticarial reaction. The five patients with ST segment elevation myocardial infarction were treated with abciximab until desensitization was complete. All but one patient underwent catheterization and 20 underwent percutaneous coronary intervention, most (66%) with the implantation of a bare metal stent. At follow-up (a minimum of 6-24 months), only two patients had discontinued aspirin, both due to gastrointestinal bleeding, and no hypersensitivy reaction had occurred. CONCLUSIONS: Aspirin desensitization is effective and safe in unstable patients with acute coronary syndrome in both the short and long term.
