Background: Several cardiovascular diseases (CVDs) are associated with hypertension (HTN) or Type 2 diabetes (T2DM). The objective of this investigation was to evaluate the pattern of cardiovascular disorders in the Saudi population associated with hypertension and T2DM.

Methodology: This descriptive study surveyed 31 community-serving primary health clinics (PHCs) in the Hail region of northern Saudi Arabia. Saudi men and women aged 18–98 who sought diabetes or hypertension medical care at PHCs were included.

Results: The overall prevalence rates of stroke, MI, CAD, and DVT were 92/1340 (6.8%), 120/1340 (9%), and 55/1340 (4.1%), respectively. The prevalence rates of stroke, MI, CAD, and DVT among T2DM were 4.5%, 5.2%, 2.2%, and 2.9%, respectively. The prevalence rates of stroke, MI, CAD, and DVT among HTN were 6.7%, 8.2%, 3.4%, and 4.5%, in that order. The prevalence rates of stroke, MI, CAD, and DVT among combined T2DM&HTN were 4.5%, 7.6%, 3.1%, and 1.8%, respectively. The risk of combined (T2DM & HTN) comorbidity to acquire CVD, the relative risk (RR), and 95% confidence interval (95%CI): RR (95%CI) = 0.6321 (0.5015 to 0.7968), P = 0.0001, z statistics = 3.884.

Conclusion: A substantial relationship was established between combined T2DM and HTN and CVD risk. MI and stroke were more likely in HTN than in T2DM, whereas DVT was more common in T2DM. The subgroup with combined T2DM and HTN had 4.5% stroke, 7.6% MI, 3.1% CAD, and 1.8% DVT. Males have a higher CVD risk (RR = 1.7825, 95% CI: 1.2503 to 2.5414, P = 0.0014). MI was the most prevalent CVD in men, followed by stroke and CAD. The most common CVD in women is DVT.
