Persistently elevated troponin I in heart failure patients - a suitable prognosticator and a possible boon to public health?

Baseline elevation of troponin I (TnI) has been associated with worse outcomes in heart failure (HF). However, the prevalence of persistent TnI elevation and its association with clinical outcomes has not been well described. HF is a major public health issue due to its wide prevalence and prognosticators of this condition will have a significant impact on public health. Methods: A retrospective study was performed in 510 patients with an initial HF admission between 2002 to 2004, and all subsequent hospital admissions up to May 2009 were recorded in a de-identified database. Persistent TnI elevation was defined as a level ≥0.05 ng/ml on ≥3 HF admissions. Baseline characteristics, hospital readmissions and all cause mortality were compared between patients with persistent TnI elevation (Persistent), patients with no persistence of TnI (Nonpersistent) and patients who had less than three hospital admissions (admission <3) groups. Also the same data was analyzed using the mean method in which the mean value of all recorded troponin values of each patient was used to define persistence i.e. patients who had a mean troponin level ≥0.05 ng/ml were classified as persistent. Results: Mean age of our cohort was 68.4 years out of which 99.6% subjects were male, 62.4% had ischemic HF. 78.2% had NYHA class III to IV HF, mean LVEF was 25.9%. Persistent elevation of TnI was seen in 26% of the cohort and in 66% of patients with more than 3 hospital admissions. Mean TnI level was 0.67 ± 0.15 ng/ml in the 'Persistent' group. Mean TnI using the mean method was 1.11 ± 7.25 ng/ml. LVEF was significantly lower in persistent group. Hypertension, diabetes, chronic renal insufficiency and mean age did not differ between the two groups. 'Persistent' patients had higher mortality (HR = 1.26, 95% CI = 0.89–1.78, p = 0.199 when unadjusted and HR = 1.29, 95% CI = 0.89–1.86, p = 0.176 when adjusted for race, LVEF and ischemic etiology) HR for mortality in persistent patients was 1.99 (95% CI = 1.06–3.73, p = 0.03) using the mean method. The following results were found in those with ischemic cardiomyopathy (HR = 1.44034, 95% CI = 0.92–2.26, p = 0.113) and (HR = 1.89, 95% CI = 1.01–3.55, p = 0.046) by using the mean method. 2 out of three patients with HF who were readmitted three or more times had persistent elevation of troponin I levels. Patients with chronic persistence of troponin I elevation showed a trend towards lesser survival as compared to patients who did not have chronic persistence, however this did not reach statistical significance. This trend was seen more among ischemic patients than non ischemic patients, but did not reach statistical significance. With the mean method, patients with chronic persistence of troponin I elevation had significantly lesser survival than those without it. Also ischemic patients had significantly lesser survival than non ischemic patients. ^

The left atrial ganglionated plexus : its function and pathways relative to atrial fibrillation surgery

Le système nerveux autonome cardiaque est devenu une cible dans les thérapies ablatives de la fibrillation auriculaire. Nous avons étudié les voies de communication et la fonction des plexus ganglionnaires (PG) de l'oreillette gauche (PGOG) afin de clarifier la validité physiopathologique des méthodes de détection et des thérapies impliquant ces groupes de neuronnes. Méthodes: Vingt-deux chiens ont subi une double thoracotomie et ont été instrumentés avec des plaques auriculaires épidcardiques de multiélectrodes. Une stimulation électrique (2 mA, 15 Hz) des PGOG a été réalisée à l'état basal et successivement après: 1) une décentralisation vagale, 2) l'ablation par radiofréquence des plexus péri-aortiques et de la veine cave supérieure (Ao/VCS) et 3) l'ablation du PG de l'oreillette droite (PGOD). Ces procédures de dénervation ont été réalisées suivant une séquence antérograde (n = 17) ou rétrograde (n = 5). Résultats: Chez 17 des 22 animaux, la stimulation des PGOG a induit une bradycardie sinusale (149 ± 34 bpm vs 136 ± 28 bpm, p < 0.002) et des changements de repolarization (ΔREPOL) auriculaires isointégrales. Dans le groupe des ablations antérogrades, les réponses aux stimulations vagales ont été supprimées suite à la décentralisation vagale chez un seul animal, par l'ablation des plexus Ao/VCS dans 4 cas et par l'ablation du PGOG dans 5 autres animaux. Des changements ont persisté tout au long chez 2 chiens. La valeur de surface des ΔREPOL a diminué avec les dénervations séquentielles, passant de 365 ± 252 mm2 en basale à 53 ± 106 mm2 après l'ablation du PGOD (p < 0.03). Dans le groupe de dénervation rétrograde, les changements de repolarisation et chronotropiques ont été supprimés suite à l'ablation du PGOD chez deux chiens et suite à l'ablation Ao/VCS chez trois. La valeur de surface du ΔREPOL a aussi diminué après l'ablation du PGOD (269±144mm2 vs 124±158mm2, p<0.05). Conclusion: Les PGOD sont identifiables en préablation par la réponse bradycardique à la stimulation directe dans la plupart des cas. Le PGOD semble former la principale, mais non la seule, voie de communication avec le nœud sinusal. Ces résultats pourraient avoir des implications dans le traitement de la FA par méthodes ablatives.
