Background The management of comorbidities is a significant component of preventive care to address the development of cardiovascular disease. Consistent care provided by a primary care physician (PCP) may be important in bridging any gender disparity in patients with comorbidities for the prevention of acute myocardial infarction (AMI). Purpose To identify gaps in established care by a PCP between genders and to evaluate the impact of comorbidities in patients who have experienced AMI. Methods Data collected for 250 total patients for this retrospective study included gender, PCP documentation, and comorbidities (hypertension, hyperlipidemia, diabetes, chronic kidney disease (CKD), arrhythmia) among patients admitted for an AMI. Data on previous MI, coronary artery bypass graft (CABG), and stent were also collected. 27 patients were excluded due to incomplete documentation. Results Out of 223 included patients, 138 (61.9%) were males and 85 (38.1%) were females with 172 (77.1%) having care by a PCP. PCP services have been utilized by 100 (72.5%) males and 72 (84.7%) females, mean age = 64.39 years. Multiple comorbidities were identified in 191 (85.7%) out of 223 patients, including 156 (81.7%) who have used PCP services and number of comorbidities varied from 1 to 5. Of these patients, 74 (43.0%) had 1-2 comorbidities: males 51 vs 23 females, and 82 patients: 41 males vs 41 females had 3-5 comorbidities that impacted their treatment and preventive care. Among the most common comorbidities were hypertension - n=165 (74.0%) and hyperlipidemia - n=157 (70.4%). Other comorbidities included diabetes - n=82 (36.8%), CKD - n=42 (18.8%), and previous arrhythmia - n=35 (15.7%). Overall, the utilization of PCP services was between 83-93% in these patients with documented comorbidities. Gender-based comparison between patients who have utilized PCP services showed that more males were diagnosed with hypertension than females: 78 vs 59, p=0.033; more males with hyperlipidemia: 75 vs 55, p=0.051; no significant difference was noticed in case of diabetes: 36 males vs 38 females (p=0.457), in case of CKD: 22 males vs 17 females (p=0.138), previous MI - 21 males vs 22 females (p=0.381), or previous arrhythmia - 19 males vs 13 females (p=0.805). The findings regarding previous procedures among those who used PCP services showed that CABG was done for 16 males vs 8 females (p=1.0), coronary stent placement – 25 males vs 21 females (p= 0.196), and significantly more males have received antiplatelet therapy - 61 vs 36 females (p=0.031). Conclusion Identification of comorbidities was significantly associated with PCP care utilization in both genders, however more males have been diagnosed with hypertension and other comorbidities. The findings show that timely identification of comorbidities is highly dependent on PCP services and is related to preventive treatment in both genders of patients who experienced AMI.
