Sense of coherence - a determinant of quality of life over time in older female acute myocardial infarction survivors

AIMS: To determine the relationships between different sense of coherence levels and quality of life, and in older female myocardial infarction survivors; to investigate how socio-demographic, clinical characteristics, sense of coherence self-reported symptoms and function affect quality of life; and to determine whether sense of coherence and quality of life are stable during a six-month follow-up. BACKGROUND: Myocardial infraction confers new physical and mental challenges. However, research on sense of coherence and other factors involved in maintaining physical, psychosocial and environmental aspects of quality of life in older female myocardial infraction survivors is scant. DESIGN: Survey. METHODS: A postal survey was conducted of 145 women, aged 62-80 years, three months to five years after myocardial infarction (T1), with a follow-up after six months (T2). Self-reported socio-demographic and clinical data and hospital medical records data were collected. The sense of coherence scale (SOC-29) and the World Health Organization Quality of Life Instrument Abbreviated (WHOQOL-BREF) were used. RESULTS: We found a significant difference in quality of life between weak, moderate, and strong sense of coherence groups (p
