Objective: Increased serum ferritin concentration can be associated with elevated oxidative stress and the development of arteriosclerosis. We evaluated the relationship between increased ferritin level and arterial stiffness in a normal population without known coronary and cerebrovascular diseases. Methods: We evaluated a total of 995 subjects (578 females; mean age: 58±8 years). After excluding subjects with known cardiovascular and cerebrovascular disease, we analyzed data from 949 subjects. Risk factors of coronary arterial disease (CAD), serum cholesterol profiles, high-sensitive C-reactive protein, fasting blood sugar (FBS) level, and ferritin concentrations were recorded. Arterial stiffness was assessed by brachial to ankle pulse-wave velocity (baPWV). Results: A univariate analysis revealed the following: baPWV was correlated with conventional clinical variables, including age (R=0.389, P<0.001), sex (R=0.099, P=0.002), blood pressure (systolic (R=0.614, P<0.001), diastolic (R=0.417, P<0.001)), triglyceride concentration (R=0.151, P<0.001), and FBS level (R=0.184, P<0.001). The baPWV was also correlated with the 10-year cardiovascular risk score (R=0.419, P<0.001) and serum ferritin concentration (R=0.184, P<0.001). The multivariate analysis demonstrated that baPWV was significantly correlated with serum ferritin concentration; this was similar to other cardiovascular risk factors, including age, blood pressure, smoking, and FBS concentration. Conclusion: Elevated serum ferritin concentration was associated with increased arterial stiffness in subjects without known coronary and cerebrovascular diseases; this may contribute to increased cardiovascular risk.

Background/Aims: The time delay for a patient from the onset of disease symptoms until the reperfusion therapy is one of the biggest interruptions in early reperfusion therapy in patients with acute ST-segment elevation myocardial infarction (STEMI). Here, we evaluated both the duration and nature of these time delays to facilitate early patient reperfusion therapy. Methods: Patients with acute STEMI who were undergoing primary percutaneous coronary intervention (PCI) were prospectively enrolled in the Chungnam National University Hospital from January 2005 to December 2007. Results: From a total 364 patients (mean age: 64±12 years) the mean time interval from the onset of symptoms to the decision to visit a hospital was 101.4±10.6 (median: 50.0) minutes. The mean time interval for the onset of disease symptoms to the patient arrival at the emergency room (ER) (pre-hospital delay) was 222.1±12.4 (median: 171.5) minutes. The mean time interval from the ER to reperfusion (door to balloon time) was 89.0±6.0 (median 65.0) minutes. The mean time interval from the onset of symptoms to successful reperfusion therapy (pain to balloon time) was 311±13.6 (median: 250) minutes. The factors associated with these significant time delays were mainly: residency in rural areas, the use of private transport in preference to an ambulance and finally the transferal of patients from other hospitals. As a result of multivariate analysis the latter was found to be the most significant causative factor. Conclusions: This study demonstrates that there is a significant pre-hospital time delay in patients with STEMI. Thus, a media campaign explaining STEMI symptoms, the importance of early visits to the emergency department, the use of an ambulance, and the activation of the base hospital for efficient patient transfer (particularly in rural areas) may reduce this time delay in patients with STEMI and avoid interruptions to otherwise efficient reperfusion therapies.
