Insights
Physicians often misjudge disease control in patients with type 2 diabetes and hypertension. The SNAPSHOT-Brazil study found low achievement of blood pressure, HbA1c, and LDL-C targets, with physicians frequently underestimating cardiovascular risk.
Area of Science:
- Cardiology
- Endocrinology
- Public Health
Background:
- Guideline targets for blood pressure (BP), hemoglobin A1c (HbA1c), and low-density lipoprotein cholesterol (LDL-C) are often unmet in patients with cardiometabolic multimorbidity (CMM).
- Physician perception of disease control frequently misaligns with guideline-defined targets.
Purpose of the Study:
- To assess real-world control of BP, HbA1c, and LDL-C in patients with type 2 diabetes (T2D) and hypertension (CMM).
- To compare guideline-based control with physician-perceived disease control and cardiovascular (CV) risk assessment.
Main Methods:
- The SNAPSHOT-Brazil study, a nationwide, multicenter, cross-sectional study, collected real-world data on patients with CMM.
- European Society of Cardiology (ESC) guidelines defined CV risk and control targets.
- Data included patient demographics, pharmacotherapy, adherence, BP, HbA1c, LDL-C levels, and physician risk/control perceptions.
Main Results:
- In 451 patients with T2D and hypertension, guideline-defined control was achieved by only 27% for BP, 34% for HbA1c, and 13% for LDL-C; 3% met all targets.
- Physicians accurately stratified CV risk in 49% of patients, underestimating it in 50%.
- Physicians overestimated disease control, particularly for BP (29%) and LDL-C (35%).
Conclusions:
- Real-world attainment of BP, HbA1c, and LDL-C targets remains low in patients with CMM, despite high pharmacotherapy use and adherence.
- Physician assessment of CV risk and disease control significantly deviates from guideline recommendations.
- Improved strategies are needed to align clinical practice with evidence-based targets for managing cardiometabolic multimorbidity.
Abstract:
Background/Objectives: The guideline targets for blood pressure (BP), hemoglobin A1c (HbA1c), and low-density lipoprotein cholesterol (LDL-C) are frequently unmet, and physicians often misjudge control. This study aimed to characterize the real-world control of BP, HbA1c, and LDL-C in patients with type 2 diabetes (T2D) and hypertension, herein called cardiometabolic multimorbidity (CMM), and to compare guideline-based versus physician-perceived disease control. Methods: We conducted SNAPSHOT-Brazil, a nationwide, multicenter, cross-sectional study to gather real-world data on patients with CMM. The ESC guidelines defined the cardiovascular (CV) risk and control targets. Results: We included 451 patients with hypertension and T2D (median age 65 years; 60% female; 54% White). Most patients (98%) were on pharmacotherapy and reported high adherence (according to the Hill-Bone Medication Adherence Scale). A very high CV risk predominated (78%); 22% of the patients were at a high risk. The guideline-defined control was achieved in 27% for BP, 34% for HbA1c, 13% for LDL-C, and 6% for both BP and LDL-C; only 3% met all three targets simultaneously. The physicians accurately stratified the CV risk in 49% of patients, while 50% had their CV risk underestimated. They systematically overestimated control in 29% of cases for BP, 35% for LDL-C, and 25% for both. The sensitivity ranged from 0.88 to 0.98; the positive predictive values ranged from 0.19 to 0.48, and the positive likelihood ratios ranged from 2.16 to 3.65. Conclusions: The SNAPSHOT-Brazil study revealed a low attainment of BP, HbA1c, and LDL-C targets, despite the widespread pharmacotherapy and the high self-reported adherence. The physicians consistently overestimated disease control and underestimated the CV risk.
