Quality of life will be measured through Minnesota Living with Heart Failure Questionnaire (MLHFQ). It is one of the most widely used health-related quality of life questionnaires for individuals with HF. It provides scores for two dimensions, physical and emotional, and a total score. The MLHFQ is a self-administered, 21-item disease-specific instrument for individuals with HF. Each item is scored in a 6-point Likert Scale (0 to 5), thus the total score could range from 0 to 105, with higher scores indicating more significant impairment in health-related quality of life. The MLHFQ has two domains; physical domain (eight items, score range from 0 to 40) and emotional domain (five items, score range from 0 to 25).

To determine reliability of MLHFQ in (URDU) language. Reliability refers to ability of a measure to produce same results administered at two or more intervals. Thus this will be test through test retest reliability
