Metal ring on 4^th or 5^th finger markedly increases both cardiac troponin I at left ventricle and cancer-related parameters such as oncogen C-fosAb2 & Integrin_-5-1 by 4-12 times. Thus these metal rings appear to promote both heart problems & cancer

We examined patients wearing a metal ring on the left 4^th finger with abnormally increased Cardiac Troponin I (which is known to increase in the presence of myocardial injury or left ventricular hypertrophy) of 5-14ng BDORT units (depending on the ring and individual) at left ventricle compared with normal value of 1ng BDORT units or less. Although shape of the ECG does not change significantly regardless of whether metal rings are on or not, when rings are on, the Bi-Digital O-Ring Test evaluation of trace of ECG revealed "Vulnerable Period of Rising Part of T-wave" of ECG waves (which correspond to the left ventricle and AV node) become abnormal with increased Cardiac Troponin I. DHEA in various parts of the body reduced significantly and maximum decrease in DHEA was found when metal ring was on the left 4 ^th and 5^th fingers. Telomere reduced with each of the 5 fingers, but the 2^nd, 4^th, and 5^th fingers produced the maximum reduction of telomere. When metal ring was inserted onto the left 1^st finger and left 2^nd finger, Cardiac Troponin I did not change significantly. Additional abnormality was found when patients with cancer wore metal ring(s); namely both Cardiac Troponin I and cancer parameters, such as Integrin-5-1 and Oncogen C-fos Ab2, increase anywhere between 4-12 times. However, when the ring was cut, creating a 1mm or longer empty space, no increase in cancer markers and Cardiac Troponin I were observed. Similar findings were found with metal bracelets.
