ABSTRACT
Left bundle branch block (LBBB) during exercise can be associated with chest pain. Though this association is mostly correlated with an underlying coronary artery disease, painful LBBB has been described in patients with normal coronary arteries. We report a case of exercise-induced LBBB with typical angina pectoris related to antimalarial prophylaxis with chloroquine in a 66-year old woman with normal coronary arteries, which was reversed after treatment discontinuation. The effect of chloroquine on the electrophysiological properties of nodal cardiac tissue is responsible for this rate-dependent LBBB. Precautions for future antimalarial prophylaxis are also discussed.

AIM: To determine the feasibility of percutaneous coronary intervention (PCI) in very old patients. BACKGROUND: The elderly are a growing population with a high prevalence of ischemic heart disease and then subsequent possibility to benefit from coronary interventions. METHOD: We have conducted a retrospective study using our PCI database since January 2000. Population characteristics, clinical presentation, type of lesions, technical procedure, immediate results and in hospital outcome are compare between patients older than 85 and the other. RESULTS: Between January 2008 and March 2009, 3130 patients benefit from coronary angioplasty. Among them, 85 patients were older than 85. There were more female in this group (24.7 vs. 14.3%, P=0.007), but no difference in cardiovascular risk profile. The older was more symptomatic (acute coronary syndrome: 59.52 vs. 44%, P=0.004; silent ischemia: 3.6 vs. 25.7%, P=0.000003). The ejection fraction was worse (EF<55%: 29.4 vs. 14.5%, P=0.0001). The lesion was more complex (B2 and C: 67.2 vs. 57.1% P=0.027) and concern more often the left descending artery (85.9 vs. 57.1%, P=0.000001). The technical success was similar in the two groups (93.28 vs. 94.32%, P=0.34) with similar rate of per procedure complications (2.35 vs. 1.5%, P=0.37). Nevertheless, the in-hospital rate mortality was higher in the older patients (7 vs 1.38%, P=0.0014). CONCLUSION: PCI is safe and safety in very old patients despite significant but acceptable increasing in-hospital mortality due to more severe disease and co morbidities. Further evaluations are necessary in order to edict specific recommendations.

PURPOSE: Evaluate heart failure management in a Military Hospital in 2005. METHODS: Retrospective audit of 46 case records of patients hospitalised with heart failure within the framework of an accreditation procedure. RESULTS: The left ventricular ejection fraction was evaluated in 85% of cases during the reference hospital stay. Systolic heart failure was detected in 63% of cases. At least one NT-proBNP assay was performed for each patient. A global assessment was systematically performed, except for the mini mental state examination in patients aged over 75 years who represented 80% of patients. Initial therapeutic education was provided for 50% of systolic heart failure patients. Prescription rates in systolic heart failure were 76% for angiotensin-converting enzyme inhibitors, 7% for angiotensin receptor antagonists; 84% for at least one medicinal product in the above 2 classes; 68% for beta-blockers and 32% for spironolactone. A hospital discharge report was available for 93% of the patients. Elective re-admissions to hospital for uptitration of treatment concerned 10% of systolic heart failure patients. Emergency hospital re-admissions after a cardiovascular event (usually decompensation), concerned 35% of patients, after an average duration of one year of follow-up. These latter re-admissions, often repeated, led to 4% of additional hospital deaths. The initial hospital mortality rate was 13%. CONCLUSION: Therapeutic patient education is under development. Medication may still be optimised, both qualitatively and quantitatively. Surveillance is planned with a yearly audit.
