摘要
Background: Increased nighttime BP variability (BPV) was associated with stroke. Left atrial (LA) enlargement is the default clinical hallmark of structural remodeling that often occurs in response to LA pressure and volume overload. Blood pressure has proven to be an essential determinant of LA enlargement. We aimed to evaluate the influence of BPV as a risk factor for cryptogenic stroke and highlight the importance of including the (APBM) in the workup for those patients and test the relation between BPV and LA remodeling in these patients, which could be used as a clue to add APM monitoring to their workup. Also, LA remodeling may be a substrate for occult atrial fibrillation (AF). We included Group I (108 consecutive patients with cryptogenic ischemic stroke) and Group II (100 consecutive adult participants without a history of stroke or any structural heart disease). We measured the maximal LA volume index (Max LAVI) and minimal LA volume index (Min LAVI). We calculated the left atrial ejection fraction (LAEF). All the participants were subjected to ABPM. Results: In our prospective, cross-sectional cohort study, the patients in Group I had statistically significantly higher Min LAVI and Max LAVI and Less LA EF than Group II, with a P value of (0.001, 0.001, and 0.008), respectively. The Group I patients had higher BPV as measured by SD parameters than patients in Group II, with a Pvalue of 0.001 for all SD parameters. The BPV parameters, as measured by SD parameters, were positively related to the LA remodeling parameters in both groups. After adjusting all variables, we found that age, night systolic SD, and night diastolic SD parameters were independent predictors of LA remodeling. Conclusions: The patients with cryptogenic stroke had higher short-term BPV, Min LAVI, and Max LAVI but lower LA EF. Careful monitoring of BPV may be of value for both primary and secondary preventions of ischemic stroke.
