The overall technical success rate of the 1269 drug-coated balloon (DCB)'s used was 99.6% (1.60 ± 0.79 DCB's/patient). At 12 months, the TLR rates were 6.3% in patients with CLI and 9.6% in claudicants, with a primary patency rate of 89.9% and 87.1%, respectively. All-cause mortality was 4.3% (28/658). The most important predictors for TLR were female gender, in-stent restenosis at baseline and lesion length. The current first-line screening test for primary hyperaldosteronism is the plasma aldosteronerenin ratio; however, renin assays have several disadvantages and the ARR is affected by medications and physiological factors. Angiotensin II is a key biologically active hormone in the renin-angiotensin-aldosterone system. It has been suggested that measurement of equilibrium levels of this peptide, involving an incubation of serum prior to analysis, may provide a better marker of renin-angiotensin-aldosterone system activity than renin. An eqAng II LC-MS/MS assay was developed, optimized and validated. Serum samples were incubated at 37°C for 45 min prior to stabilization with cold EDTA solution, solid phase extraction and LC-MS/MS analysis. Stability in whole blood and the effect of cryoactivation were assessed. For comparison to the current screening test, 150 anonymized patients' samples were analysed for eqAng II, renin activity and aldosterone (all by LC-MS/MS). The assay had good precision, minimal bias and acceptable recovery. EqAng II did not change significantly when whole blood samples were stored for up to 72 h, and cryoactivation was only observed for pregnant patients. EqAng II was significantly correlated with renin, and the aldosteroneeqAng II ratio had a strong positive correlation with the aldosteronerenin ratio. An LC-MS/MS assay for eqAng II has been developed which shows promise as an alternative screening test for primary hyp
