The 2015 „European Practicum on Cardiopulmonary exercise testing“ was held in Munich from 4th – 7th November 2015. It was a meeting with slightly more than 100 participants, newbies and experts, from all continents except South America and Antarctica.
There was a teaching course on the first three days covering all main topics of CPET. On Wednesday we started with basic exercise physiology. Besides the presentations there was a tutorial, where 10-15 participants could ask questions to one tutor from the faculty. On Thursday there was our “how to do” day. Different protocols and a standard report were presented. In two practical sessions the sponsoring industry could present their metabolic carts during constant work and ramp tests; tutors explained the measurements and their physiological background. On Friday various clinical applications of a CPET were shown. Again in specialized tutorials on different medical fields and in another laboratory session with an exercising patient, the CPET as a diagnostic tool was demonstrated.
On Saturday there was a scientific session with abstract presentations of new studies. We heard about new CPET variables, new algorithms how CPET results can be used to guide diagnostics or therapy, and some training studies.
It was an exhausting, but very interesting week, and we are looking forward to the next practicum in Milan / Italy from 26th to 28th October 2016.
(Chair of the 2015 Practicum)
From the perspective of CPX International Inc., this Practicum in Munich was a great sucess due in no small part to the energy of Professor Doctor Hager. Everything ran very well and the venue was excellent. The weather was very cold for those of us who came from Australia but we soon adapted. There were around 100 people enrolled of whom only a small number were German. This says a lot for the sucess of the advertising from Professor Doctor Hager. We received a lot of suggestions on how things could be improved from those attending. We will certainly take note of these and will implement the ideas where possible.
I and the Faculty, really would like to thank you for attending and remind you that you are now members of CPX International Inc.; as such you will receive regular abstracts of articles from many different journals on a regular basis
For the first time we have included on this page, some of the lectures in .pdf format. These can be accessed via ‘clicking’ on the appropriate link.

BACKGROUND: Remote ischemic preconditioning (RIPC) is reported to reduce biomarkers of ischemic and reperfusion injury in patients undergoing cardiac surgery, but uncertainty about clinical outcomes remains. METHODS: We conducted a prospective, double-blind, multicenter, randomized, controlled trial involving adults who were scheduled for elective cardiac surgery requiring cardiopulmonary bypass under total anesthesia with intravenous propofol. The trial compared upper-limb RIPC with a sham intervention. The primary end point was a composite of death, myocardial infarction, stroke, or acute renal failure up to the time of hospital discharge. Secondary end points included the occurrence of any individual component of the primary end point by day 90. RESULTS: A total of 1403 patients underwent randomization. The full analysis set comprised 1385 patients (692 in the RIPC group and 693 in the sham-RIPC group). There was no significant between-group difference in the rate of the composite primary end point (99 patients [14.3%] in the RIPC group and 101 [14.6%] in the sham-RIPC group, P=0.89) or of any of the individual components: death (9 patients [1.3%] and 4 [0.6%], respectively; P=0.21), myocardial infarction (47 [6.8%] and 63 [9.1%], P=0.12), stroke (14 [2.0%] and 15 [2.2%], P=0.79), and acute renal failure (42 [6.1%] and 35 [5.1%], P=0.45). The results were similar in the per-protocol analysis. No treatment effect was found in any subgroup analysis. No significant differences between the RIPC group and the sham-RIPC group were seen in the level of troponin release, the duration of mechanical ventilation, the length of stay in the intensive care unit or the hospital, new onset of atrial fibrillation, and the incidence of postoperative delirium. No RIPC-related adverse events were observed.
CONCLUSIONS: Upper-limb RIPC performed while patients were under propofol-induced anesthesia did not show a relevant benefit among patients undergoing elective cardiac surgery.

Abstract: We evaluated the feasibility of an augmented
robotics-assisted tilt table (RATT) for incremental cardiopulmonary
exercise testing (CPET) and exercise training in dependent-ambulatory
stroke patients. Stroke patients (Functional Ambulation Category ≤ 3) underwent familiarization, an incremental
exercise test (IET) and a constant load test (CLT) on separate days. A
RATT equipped with force sensors in the thigh cuffs, a work rate
estimation algorithm and real-time visual feedback to guide the
exercise work rate was used. Feasibility assessment considered
technical feasibility, patient tolerability, and cardiopulmonary
responsiveness. Eight patients (4 female) aged
58.3 ± 9.2 years (mean ± SD) were recruited and all completed the
study. For IETs, peak oxygen uptake (V’O2peak), peak heart rate
(HRpeak) and peak work rate (WRpeak) were 11.9 ± 4.0 ml/kg/min (45 % of
predicted V’O2max), 117 ± 32 beats/min (72 % of predicted HRmax) and
22.5 ± 13.0 W, respectively. Peak ratings of perceived exertion (RPE)
were on the range “hard” to “very hard”. All 8 patients reached their
limit of functional capacity in terms of either their cardiopulmonary
or neuromuscular performance. A ventilatory threshold
(VT) was identified in 7 patients and a respiratory compensation point
(RCP) in 6 patients: mean V’O2at VT and RCP was 8.9 and 10.7 ml/kg/min,
respectively, which represent 75 % (VT) and 85 % (RCP) of mean
V’O2peak. Incremental CPET provided sufficient information to satisfy
the responsiveness criteria and identification of key outcomes in all 8
patients. For CLTs, mean steady-state V’O2was
6.9 ml/kg/min (49 % of V’O2reserve), mean HR was 90 beats/min (56 % of
HRmax), RPEs were > 2, and all patients maintained the active work rate
for 10 min: these values meet recommended intensity levels for bouts of
training. The augmented RATT is deemed feasible for
incremental cardiopulmonary exercise testing and exercise training in
dependent-ambulatory stroke patients: the approach was found to be
technically implementable, acceptable to the patients, and it showed
substantial cardiopulmonary responsiveness. This work has clinical
implications for patients with severe disability who otherwise are not
able to be tested.

Background: Chronic thromboembolic pulmonary hypertension
(CTEPH) is a serious complication of pulmonary embolism
(PE). Taking into account the reported incidence of
CTEPH after acute PE, the number of patients with undiagnosed
CTEPH may be high.
Objectives: We aimed to determine
if cardiopulmonary exercise testing (CPET) could serve
as complementary tool in the diagnosis of CTEPH and can
detect CTEPH in patients with normal echocardiography.
Methods: At diagnosis, we analyzed the data of CPET parameters
in 42 patients with proven CTEPH and 51 controls, and
evaluated the performance of two scores.
Results: V E /V CO 2
slope, EQ O 2 , EQ CO 2 , P(A-a) O 2 , end-tidal partial pressure of CO 2
at anaerobic threshold (PET CO 2 ) and capillary to end-tidal carbon
dioxide gradient [P(c-ET) CO 2 ] were significantly different
between patients with CTEPH and controls (p < 0.001). P(c-ET) CO 2 was
the single parameter with the highest sensitivity
(85.7%) and specificity (88.2%). A score combining V E /V CO 2
slope, P(A-a) O 2 , P(c-ET) CO 2 , PET CO 2 [4-parameter-CPET (4-PCPET)
score] reached a sensitivity of 83.3% and a specificity of
92.2% after cross-validation. In 42 patients with CTEPH, echocardiography
identified PH in 29 patients (69%), but it was
normal in 13 patients (31%). All patients with normal or unmeasurable
right ventricular systolic pressure had a pathological
CPET. Twelve of the 13 patients (92%) were detected
by both CPET scores.
Conclusion: CPET is a useful noninvasive
diagnostic tool for the detection of CTEPH in patients with
suspected PH but normal echocardiography. The 4-P-CPET
score provides a high sensitivity with the highest specificity.

Increasing awareness of pulmonary hypertension (PH) leads to
an increased detection rate even in elderly patients with a higher rate
of comorbidities. In patients with PH and left-sided heart or pulmonary
diseases it is necessary to assess if these cardiac or pulmonary
conditions are the cause of PH or only independent comorbidities.
Additionally, it has to be evaluated if a chronic left-sided
ventricular disease with pulmonary congestion has induced a pulmonary
vasculopathy with severe PH. Sleep apnea syndrome can underlie PH and
severe PH can lead to central sleep apnea. These aspects require
experience and a careful and extensive diagnostic evaluation, including
complete hemodynamic assessment, imaging techniques, lung function and
cardiopulmonary exercise testing. Experienced PH centers should be
involved in this diagnostic process at an early stage. Although PH
leads to a worsening of the prognosis of pulmonary fibrosis and chronic
obstructive pulmonary disease (COPD) as well as of diastolic and
systolic heart failure, published data do not support targeted PH
therapies under these conditions due to a lack of evidence. Therefore,
the treatment of the underlying disease is the primary goal. Mitral
valve repair and non-invasive pressure ventilation in patients with
alveolar hypoventilation lead to hemodynamic and functional
improvement. Patients with PH and left heart disease show improvement
following normalization of volume load. So far there are no approved
medical therapies for PH due to left-sided heart disease and PH due to
lung diseases. Patients with PH and left-sided heart diseases and lung
diseases should be introduced in specific clinical studies.;
Look for this issue of the Royal College of Anaesthetics Bulletin; it is dedicated to perioperative medicine.
