Count Of MCCs |
Simple count of acute-non-cardiac related conditions.5 | Medical records | Non-CVD related conditions prevalence: 7%. Most prevalent chronic conditions were: pneumonia (18%); gastrointestinal bleeding (16%) and stroke (10%).5 |
| Simple counts of non-CVD conditions12 | Medical records. | 57% of patients had at least one non-CVD related condition. Hypertension (80%); diabetes (34%); AMI (30%) and AF (22%) were the most prevalent MCCs.12 | |
| Simple counts of CVD-related conditions.9 | Medical records; physician’s progress notes | 17% of patients had 3 or + CVD-chronic conditions. Most common dyad of CVD related conditions was: hypertension and diabetes (12%).9 | |
| Simple counts of CVD and non-CVD related conditions.10 | Medical records. | 25% of patients had 4 or + cardiac and 16% had 2 or + non-cardiac related conditions. Hypertension (75%) and renal disease(22%) were the most prevalent morbidities.10 | |
| Simple counts of CVD related conditions.18 | Medical records; patient reports. | Most prevalent MCCs were: hypertension (90%); HF (49%); AF (45%) and diabetes (48%)18 | |
| Simple counts of CVD and Non-CVD related conditions.21 | Medical records. | Most prevalent CVD related conditions were previous AMI (34%); hypertension (25%); COPD (23%); AF (22%) and diabetes (16%)21 | |
| Simple count of non-CVD related conditions.3 | Electronic medical records; clinicians reports | Most prevalent conditions were: hypertension (70%); renal disease (49%); diabetes (45%); AF (35%); COPD (34%) and psychiatric disorders (28%).3 | |
| Simple counts of MCCs14 | Cardiovascular Research Network PRESERVE study. | Most prevalent chronic conditions were: hypertension (80%); hyperlipidemia (68%); COPD (42%) and AF (38%).14 | |
| Simple counts of MCCs.22 | Investigators’ case report forms | In SOLVD prevention 46% had 2 or + MCCs. In SOLVD treatment 60% patients had 2 or + MCCs. Most prevalent MCCs: diabetes (26% vs 15%) and chronic kidney disease (41% vs 26%) in the SOLVD prevention and treatment, respectively.22 | |
| Counts and clusters of MCCS.16 | Discharge records using AHRQ software. | Average number of MCCs: 7.5. Most prevalent morbidities were: hypertension (68%); renal disease (39%); COPD (36%); diabetes (34%); anemia (28%) and AMI (16%). 16 | |
| Counts of CVD and Non-CVD related conditions.20 | Medical records. | 60% of study sample had >3 MCCs. Hypertension (82%); diabetes (29%) and COPD (20%) were the most prevalent chronic conditions.20 | |
| Indexes | Charlson and Elixhauser scores.15 | Medical records. | Hypertension (49%); arrhythmias (35%) and HF (25%) were the most prevalent chronic condtions.15 |
| Charlson index.13 | Electronic database; medical records | Charlson score of > 6 presented in 13% of the study population. Most prevalent chronic conditions: AMI (60%); hypertension (54%); diabetes (48%); AF (31%) and COPD (22%).13 | |
| Charlson index.19 | Practitioner’s reports; hospital information system | Most prevalent MCCs were: hypertension (42%); AF (39%); COPD (27%); cognitive impairment (27%) and diabetes (27%).19 | |
| Charlson index.17 | Electronic database; medical records | 76% of study sample had 1morbidity. Most prevalent morbidities were: AF (46%); ACS (40%); COPD (38%); diabetes (36%); anemia (24%); and renal disease (19%). 17 |
