There are heterogeneous data regarding the impact of diabetes mellitus (DM) and hypertension (HTN) on clinical outcomes after percutaneous coronary intervention (PCI). This study explored the effect of history of DM (hDM) and HTN (hHTN), separately and in combination with each other, on major adverse cardiac events (MACE) in short‐, mid‐, and long‐term intervals after PCI. Between 2000 and 2017, 1799 patients who had PCI were registered. They were categorized in four different groups: hDM, hHTN, hDM + hHTN, and no hDMQuery no hHTN. Incidence of myocardial infarction, revascularization, and coronary death totally considered as MACE was sought in short‐ (<24 hours), mid‐ (24 hours up to 6 months), and long‐term (more than 6 months) intervals after PCI. Among the subjects, 176 had hDM, 648 had hHTN, 370 had hDM + hHTN, and 605 were in no hDM no hHTN group. The median follow‐up time was 66.5 months. Time‐to‐event (time to the first MACE) was not significantly different between four groups. hHTN group was older and hDM group was younger at the time of enrollment PCI. Female gender was dominant only in hDM + hHTN group. Of the total, 130 patients (7.22%) experienced MACE. There was no MACE in short term, 23.07% of the MACEs were in mid‐term, and the remaining happened in long term. However, according to the rate ratio, incidence rate of MACE in mid‐tem was significantly higher than the long term. Also, MACE occurrence was significantly higher in hDM + hHTN and hHTN groups than the no hDM no hHTN group. Our study showed that the history of HTN significantly increases post‐PCI MACE rather than the history of DM. Having history of both DM and HTN synergistically raised MACE incidence. Incidence of MACE per month was higher in mid‐term than the long‐term interval.
Background Atherosclerotic cardiovascular disease (ASCVD) continues to be the first cause of mortality globally. Effective preventive strategies require focused efforts to clarify ASCVD risk factors in different subgroups of a population. This study aimed to identify individuals at higher risk of ASCVD among Shiraz University employees to guide decision-making for primary prevention. Methods This cohort-based cross-sectional study was conducted on data of 1191 participants (25–70 years old) from Shiraz University employees selected by systematic random sampling. The 10-year ASCVD risk was calculated with an ASCVD risk score estimator developed by the American College of Cardiology/American Heart Association (ACC/AHA). To analyze the data, descriptive and chi-square tests were used. All statistical analyses were conducted using the SPSS version 16.0 software. The p-value < 0.05 was considered a significant level. Results This study demonstrated that 75.3% of the participants had low risk scores, whereas 13.2% and 2.5% of them had intermediate and high risk scores, respectively. Additionally, it revealed that among women 93.7%, 2.7%, and 0.6% had low intermediate and had high risk scores, respectively, whereas among men, 61.5%, 21.1%, and 3.9% had low intermediate and high risk scores, respectively. Based on the results of the chi-square test, men were significantly more prone to ASCVD (38.5%) than women (6.3%) were. Interestingly, 40.9% of known cases of hypertension had uncontrolled blood pressure, and 62.5% of individuals without any history of hypertension, who were considered new cases of hypertension, had abnormal blood pressure. Furthermore, 38.5% of diabetic patients and 1.6% of people who did not have a history of diabetes had abnormal serum fasting blood sugar. Conclusion It was revealed that nearly 15.7% of participants were at intermediate and high risk of developing ASCVD in the next 10 years with greater risk in men. Considerably, some of hypertensive and diabetic participants had uncontrolled blood pressure and blood sugar levels, respectively. New cases of diabetes and hypertension were also recognized in our study. Therefore, to address the primary prevention of ASCVD in this population, it is necessary to have plans for targeted interventions, which can be effective in modifying their risk factors.
Background. For decades, cardiovascular diseases (CVD) have been known as men’s disease. However, recent research studies showed that they have become more common in women. Smoking is a strong risk factor for CVD especially that of coronary artery disease (CAD). Several studies reported that women are more susceptible to drastic sequels of smoking than men. There is limited data regarding the impact of smoking on post-revascularization clinical events stratified by gender. This study aimed to investigate if gender significantly changes the incidence of adverse clinical outcomes after percutaneous coronary intervention (PCI) among those with history of smoking. Methods. Participants were selected from two hospitals from 2003 to 2019. Among patients who had PCI (index PCI), those with stable CAD who underwent elective PCI were included. Exclusion criteria were defined as primary PCI and those with multiple prior revascularizations. Participants were followed up seeking for major adverse cardiac events (MACE) including revascularization (PCI or coronary artery bypass grafting), myocardial infarction, and coronary death in three time intervals according to the time of index PCI (short term: up to 24 hours, mid-term: 24 hours to less than 6 months, and long term: more than 6 months). Results. Of the 1799 patients, 61% were men and 47.08% had history of smoking (75% of the smokers were men). At the time of index PCI, smokers were significantly younger than nonsmokers. Also, MACE were significantly higher in smokers than nonsmokers, which was particularly pronounced at the long-term interval. In the nonsmokers group, there was no difference in MACE occurrence between men and women. However, of the smokers, women showed significantly higher MACE rate compared with men peers. Conclusion. Smoking makes women more prone to MACE in comparison to men among patients with stable CAD after PCI with drug-eluting stent.
Background: This study aimed to investigate the possible relationship between different stent sizes and clinical outcomes after percutaneous coronary intervention (PCI) in patients with diabetes treated with drug-eluting stents (DESs) and dual antiplatelet therapy (DAPT). Methods: Patients with stable coronary artery disease undergoing elective PCI with the DES were entered into a retrospective cohort between 2003 and 2019. Major adverse cardiac events (MACE), defined as the combined endpoint of revascularization, myocardial infarction, and cardiovascular death, were recorded. The participants were categorized according to the stent size: 27 mm for length and 3 mm for diameter. DAPT (aspirin and clopidogrel) was used for at least 2 years for diabetics and 1 year for nondiabetics. The median duration of follow-up was 74.7 months. Results: Out of 1630 participants, 29.0% had diabetes. The diabetics constituted 37.8% of those with MACE. The mean diameter of the stents in the diabetics and nondiabetics was 2.81±0.29 mm and 2.90±0.35 mm, respectively (P>0.05). The mean stent length was 19.48±7.58 mm and 18.92±6.64 mm in the diabetics and nondiabetics, respectively (P>0.05). After adjustments for confounding variables, MACE was not significantly different between the patients with and without diabetes. Although MACE incidence was not affected by stent dimensions in the patients with diabetes, the nondiabetic patients implanted with a stent length exceeding 27 mm experienced MACE less frequently. Conclusion: Diabetes did not influence MACE in our population. Additionally, stents of different sizes were not associated with MACE in patients with diabetes. We propose that using the DES supplemented by long-term DAPT and tight control of glycemic status after PCI could decrease the adverse consequences of diabetes.
