This manual aims to introduce standardized methods for data collection, analysis and quality control in epidemiological assessment and monitoring for cardiovascular diseases and to develop appropriate indicators for measuring the efficiency and impact of programmes on prevention and control of cardiovascular disease. It is designed to be usable for monitoring morbidity at the country level where data collection systems may not be very advanced. It can also serve as a useful reference in designing training materials for health workers in monitoring cardiovascular diseases, especially if used alongside the materials for risk factor surveillance produced under the WHO STEP wise approach to non-communicable diseases.
