Study summary

The purpose of the study is to assess the feasibility of Cardiac Shock Wave Treatment in patients with anginal chest pain and evidence of abnormal myocardial perfusion under stress in the absence of significant stenoses of the epicardial coronary arteries.

Read the detailed description

This is a mono-center, prospective, single arm, pilot study designed to assess the feasibility of the "Cardiac Shock Wave Treatment" in patients with anginal chest pain and evidence of abnormal myocardial perfusion under stress in the absence of significant stenoses of the epicardial coronary arteries.

A total of 10 subjects will be enrolled in the study. All enrolled study subjects will be assessed for clinical follow-up at the following intervals: 5 and 14 weeks post CSWT procedure.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • History of anginal chest pain that prompted a myocardial stress test (nuclear myocardial perfusion imaging, stress echocardiography, or perfusion CMR)
  • Evidence for stress-induced myocardial ischemia in this examination
  • Coronary angiogram showing absence of ≥30% stenosis of epicardial coronary arteries

Exclusion criteria

Exclusion Criteria:

  • Participation in other clinical trials
  • age \<18 years
  • to under cMRI
  • Contraindications to adenosine (severe (COPD), asthma, atrioventricular block (AV block) > grade 1)
  • Left ventricular thrombus
  • Uncontrolled diabetes mellitus
  • Uncontrolled arterial hypertension,
  • Any other severe chronic illness such as liver or renal failure ( (GFR) \< 45 ml/min), active neoplastic disease, history of myocardial infarction or coronary revascularization within the past three months
  • Patients with pacemaker or implanted cardioverter defibrillator
  • Patients after valve surgical replacement
  • Patients after interventional valve replacement or reconstruction (e.g. transfemoral aortic valve replacement or MitraClip implantation)
  • Pregnancy (a reliable method of must be used for the entire duration of the study)
  • Fertile female participants who are capable of bearing children and who do not use a method of contraception that is medically approved by the health authority of the respective country
  • Missing capacity to consent
Terms in these criteria, in plain language(4)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

COPD

Chronic obstructive pulmonary disease: long-term lung disease that makes it hard to breathe out, including emphysema and chronic bronchitis.

GFR and eGFR (kidney filtering)

GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².

Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
