Holter ECG findings in diabetics with medial arterial calcification
2019
OBJECTIVES: Medial arterial calcification (MAC) is a nonobstructive condition leading to reduced arterial compliance. The disease most commonly occurs in diabetes mellitus. Decreased ankle-brachial pressure index (ABI) is a well-known marker of increased cardiovascular mortality. However, also the values of ABI above 1.3, typical in MAC, are associated with increased mortality. METHODS: By means of Holter ECG monitoring, we investigated 41 patients (25 men, 16 women) with mean age of 59±8 years, suffering of type 2 diabetes mellitus and identified as having MAC, and Holter ECG monitoring with an average duration of recording 22.36 hours, was carried out by GE-Marquette MARS ECG Holter system. RESULTS: We found frequent incidence of cardiac arrhythmias and myocardial ischemia in 22 patients (53.7 %). Only 19 patients (46.3 %) had normal Holter ECG recordings. ABI values were significantly higher in patients with abnormal ECG Holter recordings. CONCLUSION: Our results confirm the importance of ABI estimation in clinical practice. As the central goal of therapy for patients with myocardial ischemia and/or complex forms of cardiac arrhythmias is the reduction or elimination of these episodes. Ambulatory Holter ECG monitoring plays an important role in the management of these patients (Tab. 7, Ref. 16).
