At the end of the run-in period the following inclusion criteria must be fulfilled:
1. Second qualifying ETT meeting all of the following criteria:
− Positivity criteria: occurrence of limiting angina and ST-segment depression
of at least 1 mm as compared to resting ECG (horizontal or down sloping and
persisting for at least 0.08 seconds after J-point, on at least three consecutive
complexes) between 2.5 and 12 minutes of initiation with modified Bruce
treadmill ergometer protocol. If the ETT is interrupted before reaching
positivity for any reason, the patient will not be included.
− Stability criteria: Difference between selection (Day -7) and inclusion
(Day 0) ETT measurements has to be within 20% of the Day 0 value.
2. At least 4 anginal attacks in the 4 week period preceding randomisation.
3. Compliance to treatment during the run-in period, i.e. placebo on top of
background treatment (calculated compliance at least 85%, in addition, patient
should not have missed more than one full daily dose).
Age limit for the study is 18 years and above
Patients will not be included in the trial if one of the following criteria applies:
General exclusion criteria:
1. Incapability of understanding the language in which the information for the patient
is given;
2. Presence or history of drug or alcohol abuse;
3. Presence of malignant disease in the past 5 years;
4. The patient is a woman of childbearing potential who does not use a reliable
method of contraception;
Note: A highly effective method of birth control is defined as those which result in
a low failure rate (i.e. less than 1% per year) when used consistently and correctly
such as implants, injectables, combined oral contraceptives, some IUDs, sexual
abstinence or vasectomised partner.
5. The patient is a pregnant or breast feeding woman;
6. Participation in a concurrent clinical trial or in another trial within the past 4 weeks;
7. Repeated participation in this trial;
8. Anticipated poor medication compliance;
9. The patient is the investigator him/herself.
Trial-specific exclusion criteria:
1. Recent acute myocardial infarction, coronary bypass surgery less than 3 months
before inclusion or coronary angioplasty less than 6 months before inclusion;
2. Unstable angina, Prinzmetal angina or microvascular angina;
3. Angina pectoris symptoms typically induced by factors other than physical
exertion;
4. Known high-grade left main coronary artery disease that has not been surgically
bypassed or mechanically improved;
5. History of untreated, clinical relevant mitral insufficiency, constrictive pericarditis,
pericardial tamponade, severe pulmonary hypertension, aortic stenosis,
hypertrophic obstructive cardiomyopathy or other causes of left ventricular outflow
tract obstruction. If such disorders are treated, the treatment should be confirmed
by echocardiogram not older than 6 months. The clinical relevance of the
disorders is left to the discretion of the investigator;
6. Hyperresponsitivity or contraindications to nitrovasodilators in particular PETN
and nitroglycerin;
7. Anticipated elective percutaneous transluminal coronary angioplasty (PTCA) in
the upcoming 12 weeks;
8. Patient who cannot perform exercise tests, in particular for muscular, joint and/or
skeletal reasons;
9. Clinically significant heart disease other than coronary artery disease;
10. Congestive heart failure stage III or IV New York heart association (NYHA);
11. Symptomatic hypotension (100mmHg, dizziness, orthostatic dysregulation);
12. Uncontrolled hypertension (systolic blood pressure at rest at above 180 mmHg or
diastolic blood pressure at rest above 100 mmHg);
13. Atrial fibrillation, flutter, pacemaker or cardioverter-defibrillator implantation;
14. ECG abnormalities that would confound ETT interpretation;
15. Repolarisation disturbance seen in the ECG at baseline;
16. Hepatic disorders (alanine aminotransferase [ALT] more than 3 times normal
value), renal failure (serum creatinine level above 180 μmol/l);
17. Electrolyte disorders;
18. Anaemia (haemoglobin below 10.0 mg/dl);
19. Thyroid disorders (unless stable and controlled by thyroxin treatment for at least
3 months);
20. Any treatment with unautho
