E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
Hypertrophic obstructive cardiomyopathy |
|
E.1.1.1 | Medical condition in easily understood language |
Hypertrophic cardiomyopathy (HCM) is a condition in which a portion of the heart becomes thickened without an obvious cause. This results in the heart being less able to pump blood effectively. |

E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
We want to quantify the effect of metoprololsuccinat on myocardial function, hemodynamics and symptoms in patients with hypertrophic obstructive cardiomyopathy. |
|

|
E.2.3 | Trial contains a sub-study | No |

E.5 End points |
E.5.1 | Primary end point(s) |
The primary endpoint is the reduction in Pulmonary Capillary Wedge Pressure (PCWP).
|
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
The randomization codes will be unblinded when 27 patients with HOCM have finished full trial participation, after this the endpoint will be evaluated. Final endpoint evaluation is estimatede to 18-24 months after the first patient have been enrolled.
|
|
E.5.2 | Secondary end point(s) |
The secondary endpoint is the increase in oxygen consumption, coronary flow reserve and mechanical efficiency and the reduction in interventriculare pressure gradients during exercise, NT-proBNP, heart failure symptoms and improvement of lifequality. |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
The randomization codes will be unblinded when 27 patients with HOCM have finished full trial participation, after this the endpoints will be evaluated. Final endpoint evaluation is estimatede to 18-24 months after the first patient have been enrolled. |
