Subclinical hyperthyroidism is not associated with progression of cardiac mass and development of left ventricular hypertrophy in middle‐aged and older subjects: results from a 5‐year follow‐up
Abstract
Summary: Background Decreased serum TSH levels are associated with increased cardiovascular mortality in elderly, and subclinical hyperthyroidism (SCH) was associated with left ventricular hypertrophy (LVH) as a predictor of cardiovascular mortality in some cross‐sectional and case‐control studies. The aim was to assess whether SCH independently impacts development of LVH over time. Methods Of 3300 participants of the population‐based Study of Health in Pomerania those with overt hyperthyroidism, hypothyroidism, possible thyroid disease or missing echocardiographic baseline data or follow‐up were excluded, resulting in a study population of 1112 individuals (556 women) aged 45–81 years. Echocardiographic left ventricular mass divided by height 2·7 (LVMI ht), and LVH ht (LVMI ht >44 g/m 2·7 in women and >48 g/m 2·7 in men) was measured at baseline and after 5‐year follow‐up (median 5·00; range 4·92; 5·08). Comparison of subjects with (n = 107) and without (n = 1005) SCH were made by linear and logistic regression models adjusted for age, gender, smoking status, hypertension, and waist circumference. Results At follow‐up, LVMI ht did not differ between subjects with and without SCH (50·2 g/m 2·7, interquartile range (IQR) 41·2; 59·5 vs 47·8 g/m 2·7, IQR 39·3; 56·9; P = 0·29). LVH ht was present in 66 (61·7%) subjects with and 543 (54·0%) persons without SCH (P = 0·13). Analyses revealed no association between SCH and progression of LVMI ht (β = −0·18; 95%‐confidence interval (CI) −2·34; −1·99; P = 0·873), and development of LVH ht (relative risk 0·86, 95%‐CI 0·60; 1·26; P = 0·462), respectively. Conclusions In this population‐based sample, SCH had no impact on progression of LVMI and development of LVH during 5‐year follow‐up in subjects aged 45 years or older.

Two recent prospective studies did not find a link between subclinical hyperthyroidism and left ventricular mass in elderly subjects.
“On the other hand, two recent prospective studies did not find a link between SHyper and left ventricular mass in elderly subjects [69,70] , almost certainly because SHyper has not been associated with symptoms of adrenergic overactivity in the elderly [50] .”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
