Introduction Globally, one of the main causes of maternal and perinatal deaths is hypertensive disorders of pregnancy (HDP). Preeclampsia is a pregnancy-specific syndrome characterized by high blood pressure and proteinuria after 20-week gestation. Women who develop preeclampsia are at increased risk for the development of many systemic complications. Materials and methods A cross-sectional study was conducted in the Department of Biochemistry, SHKM, Nuh, Haryana in collaboration with the Department of Obstetrics & Gynecology. 200 study subjects; Group 1: cases - 100 HDP, Group 2: controls - 100 age-matched normotensive pregnant women. The specimen of 3 mL venous blood was collected under aseptic precautions. The data was evaluated using statistical evaluation tools. Result Out of 200 subjects, mean C-reactive protein (CRP) levels were normal in three cases and 35 controls. Minor elevation of CRP was observed in 11 cases and 29 controls (very significant). Moderate elevation of CRP was observed in 61 cases and 36 controls (highly significant). Marked elevation of CRP was observed in 25 cases. Mean CRP levels increased from preeclampsia without severe features (3.9 mg/dL), preeclampsia with severe features (5.2 mg/dL), and eclampsia (12.7 mg/dL) when compared with the respective control group (1.1 mg/dL, 1.16 mg/dL, and 1.2 mg/dL). Conclusion There is a highly significant association between CRP levels and HDP. Additionally, one useful indicator of the severity of preeclampsia is CRP, a measure of systemic inflammation. Elevated CRP levels in mild PE can be used as an indicator of the progress of the disease and early prevention can be done.

Blood Studies for Cardiovascular System II: CRP, Hcy, and Cardiac Natriuretic Peptide Markers

Cardiac biomarkers are critical in diagnosing, prognosing, and managing cardiovascular diseases. Routine measurement of specific biomarkers such as B-type natriuretic peptide (BNP), C-reactive protein (CRP), and homocysteine (Hcy) is common practice in clinical settings to evaluate heart function and predict cardiovascular events.
These markers indicate stress or strain on the heart muscle:
Natriuretic Peptides (BNP)
Cardiac myocytes produce these hormones in response to ventricular stretching...

Hormonal Regulation01:33

Hormonal Regulation

The renin-aldosterone system is an endocrine system which guides the renal absorption of water and electrolytes, thus managing blood pressure and osmoregulation. Activation of the system begins in the kidneys with a small cluster of cells adjacent to the afferent and efferent blood vessels of the renal corpuscle. As the nephrons are filtering blood, juxtaglomerular cells monitor blood pressure. If they detect a decrease in pressure, they release the hormone renin into the bloodstream.

Hypertension and Regulation of Blood Pressure01:18

Hypertension and Regulation of Blood Pressure

Hypertension, the most common cardiovascular disease, is diagnosed through repeated measurements of elevated blood pressure. Its risks, including damage to the kidney, heart, and brain, are directly proportional to blood pressure levels. Starting from 115/75 mm Hg, the risk of cardiovascular disease doubles with each increment of 20/10 mm Hg. The diagnosis relies on blood pressure measurements, not on patient symptoms, as hypertension is often asymptomatic until end-organ damage is imminent or...

Special considerations while measuring blood pressure

When assessing blood pressure (BP), healthcare professionals must consider various factors and potential unexpected outcomes to ensure accurate readings and provide proper patient care. Adhering to these guidelines is essential to achieving the most reliable results.
Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.

Measurement of Blood Pressure01:17

Measurement of Blood Pressure

Assessing blood pressure is a standard procedure executed in virtually all medical environments. The method utilized today was established over a hundred years ago by an innovative Russian doctor, Dr. Nikolai Korotkoff. The soft ticking noise, known as Korotkoff sounds, heard while taking blood pressure readings results from turbulent blood flow within the vessels. The apparatus required for this procedure includes a sphygmomanometer, a blood pressure cuff attached to a gauge, and a...

Antihypertensive Drugs: Angiotensin-Converting Enzyme Inhibitors01:30

Antihypertensive Drugs: Angiotensin-Converting Enzyme Inhibitors

Angiotensin-converting enzyme (ACE), a vital component of the renin-angiotensin-aldosterone system, is abundant in lung endothelial cells. ACE converts the inactive decapeptide, angiotensin I, into the active octapeptide, angiotensin II. This potent vasoconstrictor narrows blood vessels, increasing resistance to blood flow and elevating blood pressure. Angiotensin II also stimulates aldosterone production, encouraging kidney cells to reabsorb more sodium and water from urine, thereby increasing...
