Effect of Vitamin D and parathyroid hormone levels on the coronary slow-flow phenomenon

What Was Tested

Researchers studied Parathyroid Hormone (PTH 1-84) in this observational study publication.

Blood samples were taken to determine the calcium, phosphorus, 25-hydroxy vitamin D, and parathyroid hormone levels.

Why It Was Studied

Variations in vitamin D, and parathyroid hormone levels may affect coronary flow and cause the coronary slow-flow phenomenon (CSF).

Who Took Part

The study group was 93 patients.

The age groups tagged for this paper are middle-aged adults and older adults, both men and women.

The researchers enrolled 93 patients who had undergone coronary angiography and had near-normal coronary arteries.

How the Study Was Run

Vitamin D deficiency was defined as a serum 25-hydroxy vitamin D level of less than 20 ng/mL.

The researchers divided the study population into two groups according to thrombolysis in myocardial infarction frame count (TFC) levels.

What Was Measured

Variations in vitamin D, and parathyroid hormone levels may affect coronary flow and cause the coronary slow-flow phenomenon (CSF).

PubMed files the paper under topics including Calcifediol, Calcium, Coronary Angiography, Coronary Circulation, Coronary Vessels, Cross-Sectional Studies and Myocardial Infarction.

The authors tagged it with the keywords 25-hydroxyvitamin D, coronary artery disease, parathyroid hormone and vitamin D.
