    Laryngoscope, 2009
    Co-Authors: Hanna Tervonen, Minna M Niskanen, Anssi Sovijarvi, Auli S Hakulinen, Erkki Vilkman, Leenamaija Aaltonen
    Abstract:

    Objectives/Hypothesis: Exercise-induced vocal cord dysfunction is difficult to diagnose because the paradoxical vocal cord adduction should be observed during exercise. Our goal was to develop and validate a new diagnostic method for exercise-induced vocal cord dysfunction by combining continuous fiberoptic laryngoscopy with a Bicycle Ergometry test. Methods: Thirty consecutive patients referred to a laryngologist because of suspicion of exercise-induced vocal cord dysfunction and 15 healthy controls underwent the exercise test until dyspnea or exhaustion rated as 18–19/20 on the Borg scale. Laryngeal findings, electrocardiography, blood pressure, heart rate, and respiratory rate were monitored, and forced expiratory flow in the first second was measured before and after the exercise. The medical history was assessed by use of a structured questionnaire. Results: Among the 30 patients, 27 (90%) performed the test successfully, as did all controls. Diagnostic signs of inspiratory stridor, supraglottic collapse, and vocal cord adduction appeared in five (19%) patients but in none of the controls. Of the 30 patients referred, the laryngologist considered 25 to be suspect. Of them, 9 (36%) showed signs diagnostic or highly suspect for exercise-induced vocal cord dysfunction. Of the 15 patients whose dyspnea could be induced during the test, nine (60%) were suspected of having exercise-induced vocal cord dysfunction. Conclusions: Fiberoptic videolaryngoscopy during Bicycle Ergometry was a well-tolerated and relatively easily established diagnostic tool that could induce dyspnea in more than one half the patients examined. If the symptom of dyspnea appeared, the most frequent diagnosis was exercise- induced vocal cord dysfunction. Laryngoscope, 2009

  • Interrelation of ST-segment depression during Bicycle Ergometry and extent of myocardial ischaemia by myocardial perfusion SPECT.
    European journal of nuclear medicine and molecular imaging, 2009
    Co-Authors: Stefano Muzzarelli, Matthias Pfisterer, Jan Müller-brand, Michael J. Zellweger
    Abstract:

    The aim of this study was to compare ST-segment depression (STD) during Bicycle Ergometry and extent of myocardial ischaemia assessed by myocardial perfusion SPECT (MPS) in a large patient cohort. Consecutive patients (n = 955) referred for MPS with Bicycle Ergometry and interpretable stress ECG were evaluated with respect to ECG and MPS findings of ischaemia. The maximal STD was recorded and exercise ECG was considered ischaemic if STD was horizontal or downsloping (>or=1 mm). MPS was interpreted using a 20-segment model with a scale of 0 to 4. A summed stress (SSS), summed rest (SRS) and summed difference score (SDS = SSS-SRS, e.g. extent of ischaemia) were derived. Ischaemia was defined as an SDS >or= 2. An exercise-induced STD was present in 215 patients (22%) and myocardial ischaemia on MPS was present in 366 patients (38%). The extent of ST-segment depression and the number of ECG leads with significant STD were each strongly and significantly associated with increasing severity of ischaemia and the number of coronary territories involved (p < 0.01 for all correlations). These data demonstrate a strong correlation between the extent of STD, number of ischaemic leads and severity of myocardial ischaemia as assessed by MPS during Bicycle Ergometry.
