- "Vital exhaustion," characterized by fatigue, irritability, and demoralization, precedes new and recurrent coronary events. Biological mechanisms explaining this association are not fully understood. The objective was to investigate the relationship between vital exhaustion, lifestyle, and lipid profile. Vital exhaustion, smoking, body mass index (BMI), alcohol consumption, exercise capacity, and serum lipids were determined in 300 healthy women, aged 56.4 +/- 7.1 years. No statistically significant associations were found between vital exhaustion and lifestyle variables. Divided into quartiles, vital exhaustion was inversely related to high-density lipoprotein cholesterol (HDL-C) and apolipoprotein A1 in a linear fashion after adjustment for age, BMI, exercise capacity, and alcohol consumption. A multivariate-adjusted vital exhaustion-score in the top quartile, as compared to one in the lowest, was associated with 12% lower HDL-C and 8% lower apolipoprotein A1 (p < .05). In conclusion, alterations in lipid metabolism may be a possible mediating mechanism between vital exhaustion and coronary heart disease. The impact of lifestyle variables was weak.

- The objective of this study was to investigate the prospective impact of vital exhaustion on recurrence after acute myocardial infarction (AMI) in women. Women ≤ 65 years, mean age = 55.30, SD = 7. 63, N = 110, consecutively admitted to a coronary care unit with AMI were examined after three-six months, and followed for five years. Vital exhaustion was assessed using an early version of the Maastricht Questionnaire. A recurrent event was defined as cardiac death, AMI or a revascularization procedure. Forty-five recurrent events were found (in 41% of the study group). One standard deviation (8.4 points) increase of vital exhaustion scores was associated with a 53 % increased risk of a new event and a score above the median was associated with a hazard ratio of 2.24 (95% CI 1.21-4.14). These results remained after adjusting severity of chest pain and significant coronary stenosis. In conclusion, it was found that vital exhaustion is a marker of poor prognosis in women with AMI. The relationship appears to be independent of signs of underlying disease, including severity of chest pain and significant coronary stenosis.
