16 Possible Causes for Onset of Symptoms in the Fourth to Sixth Decade of Life, Progressive Biatrial Enlargement

  • Atrial Standstill

    An asymptomatic patient with cardiomegaly caused by isolated right atrial standstill is reported. The right atrium showed no evidence of contraction on pressure records or angiographically, while the left atrium functioned normally.[ncbi.nlm.nih.gov]

  • Restless Legs Syndrome

    Although one third of patients are affected before the age of 20 years, clinical presentation typically occurs between the fourth and sixth decades of life, when sensory symptoms[dx.doi.org] […] of disease, sensory symptoms are mild and punctuated by asymptomatic periods of variable duration.[dx.doi.org] […] age-dependent expressivity; the influences of anemia, uremia, diabetes, and peripheral neuropathy; and possibly the modulation of phenotype by body iron stores. 18 At the onset[dx.doi.org]

  • Recurrent Corneal Erosion

    The first stage is the onset of cornea guttata, usually in the fourth decade of life. Subjective symptoms rarely occur until the fifth or sixth decade.[emedicine.com]

    Restrictive cardiomyopathy is an uncommon primary cardiomyopathy characterized by biatrial enlargement, normal or decreased biventricular volume, impaired ventricular filling[ncbi.nlm.nih.gov] Patients may present with a variety of clinical phenotypes, ranging from a complete absence of symptoms to a rapid, progressive decline in LV systolic and diastolic function[ncbi.nlm.nih.gov]
