Abstract
Introduction. Nonmodifiable cardiovascular risk factors, like age and sex, are easily quantifiable. Due to immense technical progress in diagnostics and medical data storage, the aim of this study was to quantify, verify, and to compare parental cardiovascular events (CVE) as an additional nonmodifiable risk factor for young and middle-aged ischaemic stroke patients and controls. Methods. Information about parental CVE was first obtained by standardized questionnaires answered by 385 acute ischaemic stroke patients (15-60 years of age) and 260 controls. After consent to contact living and include deceased parents, patients and controls provided necessary personal identification of their parents. Thereafter, CVE were verified by standardized questionnaires answered by parents or medical records in case of deceased parents. Results. One hundred-and-nine (14.2) of 770 patient parents vs. 128 (24.6) of 520 control parents were not available for verification. Active participation was obtained for 229 (73.9) of 310 patient parents vs.113 (58.2) of 194 control parents. Medical record verification was obtained for 192 (54.7) of 351 deceased patient parents, vs.103 (52.0) of 198 deceased control parents. This study showed highest death rates of fathers (65.3 patient fathers and 57.6 control fathers) and highest numbers of CVE, especially myocardial infarction among patient fathers of patients aged 50-60 years. Discussion and Conclusion. Obtaining verified parental CVE as a nonmodifiable risk factor is still challenging, despite widely available digital medical information. To attain more accurate information on parental CVE, we recommend active involvement of family members in addition to medical record verification, especially for patients aged 50 years. Trial Registration. This trial is registered with NCT01597453
