1 tablet of Aspirin 75 mg administered x 1 daily for 7 days.

All patients with HLA antibodies receive 4 ECP-treatments in 2 months.

The control group does not receive ECP-treatments, but blood samples are drawn at the same intervals as treatment group and CAG+OCT are also performed at baseline and 12 months follow up as the treatment group.

Patients with antibodies receive 4 ECP-treatments if they have CAV. If patients do not want to receive ECP-treatments, they are allocated to the control group, which do not receive ECP-treatments.
All patients receive 7 days treatment with aspirin and blood samples are drawn before and after.

Eleven participants will be vitamin D deficient with LDL-C between 100 to 130mg/dl.
This arm will receive Simvastatin 40 mg once daily and placebo once weekly, and will perform moderate intensity exercise for twelve weeks. Participants will be advised to walk a minimum of 3000 steps in 30 minutes on 5 days each week

Peak oxygen consumption (VO2peak) is defined as highest rate at which oxygen can be taken up and utilized by body during severe exercise during bicycle ergometry The participants were encouraged to exercise to exhaustion with progressive 2-minutes increments in the power output during the test. VO2peak was obtained when participants reached volitional exhaustion and met one of the following criteria: plateau in oxygen consumption despite increase in workload, rating of perceived exertion >18, Respiratory exchange ratio > 1.10 and peak heart rate within 10 beats of age predicted maximum.

Peak oxygen consumption(VO2peak)

As VO2peak (expressed as liters of oxygen consumed per minute) is also dependent on age, sex, and body size, it was also expressed as percentage of the predicted value(VO2peak%).

Peak oxygen consumption percentage of predicted value (VO2peak%)

Skeletal muscle citrate synthase activity is a validated marker of mitochondrial content.Skeletal muscle biopsy is obtained from vastus lateralis muscle of five patients in either groups before and after the intervention. Under aseptic conditions, samples were taken in protease inhibitor cocktail and stored at -80ºcelsius. Mitochondrial citrate synthase activity (the working range of the kit was 1.56-100 µg/mL, with intra and inter assay coefficient of variation (CV) of 4.35-6.55 % and 8.3 % respectively) is measured using ELISA Kit (Abcam, Cambridge, UK) as per manufacturer's instructions.
