Stress exercise

Educate the patient about lifestyle changes that will improve symptoms of anxiety. These include adequate sleep and exercise, stress management, meditation, and coping skills.

The endogenous analgesic system is normally inactive. It remains unclear how this system becomes activated. Potential activating factors include exercise, stress, acupuncture, and hypnosis. 

The safety of G-CSF stimulation in patients with CAD has been questioned in two recent studies. Hill et al. [138] report the results of administration of 10 mcg/kg/day of G-CSF for 5 days in patients with chronic CAD n = 16). There was no clinical benefit as assessed by exercise stress testing and dobuta-mine cardiac MRI. Additionally two patients in the G-CSF group developed serious adverse events related to the therapy (one non-ST elevation MI one MI causing death). Zbinden et al. [139] also tested the efficacy of the same G-CSF dose in patients with chronic CAD ( = 7). The invasive endpoint collateral flow index was significantly better in the G-CSF treated patients when compared to the placebo group. However, two patients in the G-CSF treated group developed acute coronary syndrome during treatment. 

All patients were asked to return to the investigative site for a clinical visit four weeks one-week postprocedure to repeat clinical labs and monitor acute clinical events. All patients were contacted by telephone by the investigative site at three months one week for a safety evaluation. All subjects were required to return to the investigative site for a repeat coronary angiography whether they were experiencing symptoms or not. If a patient had a positive exercise stress test at any time up to and including his required follow-up, a repeat angiogram was performed. 

Transient myocardial ischemia was evaluated in 112 patients undergoing the Bruce protocol exercise stress testing. Technetium tetrofosmin scans were obtained and BNP levels were assessed before, during, and four hours after exercise (13). If patients had no inducible ischemia, BNP levels were low at baseline, 43 pg/mL, and unchanged during and after exercise. However, in patients with inducible ischemia, BNP levels rose from a median 62 to 92 pg/mL and nearly returned to baseline at four hours postexercise, Patients with severe ischemia had median BNP levels at baseline, 101 pg/mL and increased to 123 pg/mL, These were still elevated four hours postexercise to I 15 pg/mL, Differences were based on the BNP levels, Patients with no ischemia (43 pg/mL), mild to moderate ischemia (60-92 pg/mL), and severe ischemia (101 pg/mL) were statistically different, These differences were increased with exercise stress (13),...

There is another and more general solution to the problem, called the predictive approach " Starting from a set of ordinary reference values and using quantitative information on the effect of various factors, such as intake of food, alcohol, and drugs exercise stress or posture, we could estimate expected reference values that fit the actual clinical setting (see Chapter 17). ... 

Laboratory tests are affected by many factors, such as recent intake of food, alcohol, or drugs, and by smoking, exercise, stress, sleep, posture during specimen collection, and other variables (see Chapter 17). Proper patient preparation is essential for the test results to be meaningful. Although responsibility for this usually resides with personnel outside the laboratory, the laboratory must define the instructions and procedures for patient preparation and specimen acquisition. These procedures should be included in hospital procedure manuals and should be transmitted to patients in both oral and written instructions. Compliance with these instructions is monitored directly when the laboratory employs its own phlebotomists. Specific inquiry should be made regarding patient preparation before specimens are collected, and efforts should be made to correct noncompli-ance. For tests in which standardization of the collection is very important (such as for plasma catecholamines), specimens should be collected in a controlled environment, such as a clinical testing unit.

Lastly, the VR lead may also be useful in detecting multivessel disease during the exercise stress test (Michaelides et al, 2003). 

The occurrence of false-positive cases of ST-segment depression during an exercise stress test has already been addressed. These are due to different causes (hyperventilation, drugs, etc.) or are of unknown origin (Table 4.5 and Figure 4.58). In some circumstances (neurocirculatory asthenia, hyperventilation, etc.), their origin is unknown or difficult to explain.

Some sophisticated techniques (CMTCE) or isotopic techniques are not available in the emergency department of majority of the centres. However, X-ray, exercise stress test, repeated determination of troponin levels and even an echocardiographic study can be performed in many of them. An exercise stress test should be carried out to clarify diagnostic doubts but only when a proper history and review of previous ECG recordings, if available, have ruled out that the patient is clinically unstable. The few serious problems that may arise during the practice of exercise test in these patients usually occur because these considerations have not been borne in mind (Ellestad, 2004). An example of the usefulness of the exercise stress test in a... 

In a small percentage of cases diagnosis is not clearly performed, and the patient s evolution sometimes provides the solution. When the clinical picture, the ECG recording, the enzymatic levels and the exercise stress test are not conclusive and the final diagnosis is an ACS, it is generally of low risk (Lee et al., 1985,1993 Pastor Torres et al, 2002). The complication rate of an ACS with a normal baseline ECG that shows no changes during a chest pain episode is quite low. On the other hand,...
