ABSTRACT

Limited and inconsistent data are present regarding the importance of the time delay between symptom onset and balloon inflation in ST-segment elevation myocardial infarction (STEMI) patients. We aimed to investigate the possible influence of prolonging pain-to-balloon times (PBT) on in-hospital outcomes and mortality in a large cohort of patients with STEMI undergoing primary percutaneous coronary intervention. We retrospectively studied 2,345 STEMI patients (age 61 ± 13 years, 82% men) who underwent primary percutaneous coronary intervention. Patients were stratified according to PBT into 3 groups: ≤120 minutes, 121 to 360 minutes, and >360 minutes. Patients' records were assessed for the occurrence of in-hospital complications, 30-day, and 1-year mortality. Of the 2,345 study patients, 36% had PBT time ≤120 minutes, 40% had PBT of 121 to 360 minutes and 24% had PBT time >360 minutes. The major part of the total PBT (average 358 minutes) was caused by the time interval from symptom onset to hospital arrival, namely, pain-to-door time (average 312 minutes) in all 3 groups. Longer PBT was associated with a lower left ventricular ejection fraction, higher incidence of in-hospital complications, and higher 30-day mortality. In 2 multivariate cox regression models, a per-hour increase in PBT (hazard ratio 1.03 [95% confidence interval 1.00 to 1.06], p = 0.039) as well as PBT >360 minutes (hazard ratio 1.6 [95% confidence interval 1.1 to 2.5], p = 0.04) were both independently associated with an increased risk for 1-year mortality. In conclusion, PBT may be an accurate and independent marker for adverse events, pointing to the importance of coronary reperfusion as early as possible based on the onset of pain.

ABSTRACT

BACKGROUND: Tricuspid regurgitation (TR) is associated with adverse prognosis in various patient populations, but currently no data is available about the prevalence and prognostic implication of TR in ST-segment elevation myocardial infarction (STEMI) patients. OBJECTIVES: To investigate the possible implication of TR among STEMI patients. METHODS: We conducted a retrospective study of STEMI patients undergoing primary percutaneous coronary intervention (PCI) and its relation to major clinical and echocardiographic parameters. Patient records were assessed for the prevalence and severity of TR, its relation to the clinical profile, key echocardiographic parameters, in-hospital outcomes, and long-term mortality. Patients with previous myocardial infarction or known previous TR were excluded. RESULTS: The study included 1071 STEMI patients admitted between September 2011 and May 2016 (age 61 ± 13 years; predominantly male). A total of 205 patients (19%) had mild TR while another 32 (3%) had moderate or greater TR. Patients with significant TR demonstrated worse echocardiographic parameters, were more likely to have in-hospital complications, and had higher long-term mortality (28% vs. 6%; P < 0.001). Following adjustment for significant clinical and echocardiographic parameters, mortality hazard ratio of at least moderate to severe TR remained significant (hazard ratio 2.44; 95% confidence interval 1.06-5.62; P = 0.036) for patients with moderate-severe TR. CONCLUSIONS: Among STEMI patients after primary PCI, the presence of moderate-severe TR was independently associated with adverse outcomes and significantly lower survival rate.

ABSTRACT

BACKGROUND: The Vegetative State (VS) is a severe disorder of consciousness in which patients are awake but display no signs of awareness. Yet, recent functional magnetic resonance imaging (fMRI) studies have demonstrated evidence for covert awareness in VS patients by recording specific brain activations during a cognitive task. However, the possible existence of incommunicable subjective emotional experiences in VS patients remains largely unexplored. This study aimed to probe the question of whether VS patients retain a brain ability to selectively process external stimuli according to their emotional value and look for evidence of covert emotional awareness in patients. METHODS AND FINDINGS: In order to explore these questions we employed the emotive impact of observing personally familiar faces, known to provoke specific perceptual as well as emotional brain activations. Four VS patients and thirteen healthy controls first underwent an fMRI scan while viewing pictures of non-familiar faces, personally familiar faces and pictures of themselves. In a subsequent imagery task participants were asked to actively imagine one of their parent's faces. Analyses focused on face and familiarity selective regional brain activations and inter-regional functional connectivity. Similar to controls, all patients displayed face selective brain responses with further limbic and cortical activations elicited by familiar faces. In patients as well as controls, Connectivity was observed between emotional, visual and face specific areas, suggesting aware emotional perception. This connectivity was strongest in the two patients who later recovered. Notably, these two patients also displayed selective amygdala activation during familiar face imagery, with one further exhibiting face selective activations, indistinguishable from healthy controls. CONCLUSIONS: Taken together, these results show that selective emotional processing can be elicited in VS patients both by external emotionally salient stimuli and by internal cognitive processes, suggesting the ability for covert emotional awareness of self and the environment in VS patients.
