Cardiovascular disease: causes, prevention, and what to watch for

High blood pressure and clogged arteries quietly raise your risk of heart attack and stroke. You might not feel anything until a problem happens, so knowing the basics can save time, money, and your health. This page pulls together practical steps, common medicines, and red flags so you can act fast when it matters.

Quick actions you can take today

Check these simple things first: measure your blood pressure, know your total cholesterol, and get an A1c if you have diabetes. Small changes add up — cut back on salt, swap sugary drinks for water, walk 20–30 minutes most days, and stop smoking. If you’re overweight, losing 5–10% of body weight often drops blood pressure and improves cholesterol.

Set reminders for routine checks. Many clinics offer quick BP readings without an appointment. If you already take medications, keep an up-to-date list and bring it to every visit.

Medications and what to watch for

Doctors commonly use blood pressure medicines (ACE inhibitors, ARBs like irbesartan), statins for cholesterol, and drugs that thin the blood when needed. Each drug class has its own risks and simple safety steps. For example, some people taking ARBs report allergic reactions or swelling of the face and throat (angioedema). If you notice sudden swelling, trouble breathing, or a rash after a new medicine, seek emergency help.

Routine blood tests matter. Many heart medicines affect kidney function and potassium levels, so your doctor will test these soon after you start a new drug and then at intervals. If you buy meds online, use licensed pharmacies and keep prescriptions—fake or low-quality drugs can cause harm.

Think about the whole picture. Diabetes medicines and thyroid or hormone treatments can change heart risk and interact with other drugs. If you manage multiple conditions, ask your clinician to review all your medications together.

Know emergency signs: sudden chest pain or pressure, pain radiating to the arm or jaw, sudden shortness of breath, fainting, or sudden weakness on one side of the body. Call emergency services immediately if any of those happen.

Finally, make follow-ups routine. A clear plan with your clinician—targets for BP, LDL cholesterol, and blood sugar—keeps you on track. Small, steady steps prevent most serious events and let you live better with less worry.
