Swelling of the legs in the case of cardiovascular diseases
A sedentary lifestyle, alcohol, and cigarette consumption increase body weight which in turn hinders healthy blood circulation and strength of arteries and veins. This results in high blood pressure. So, if you’re overweight, you need to monitor your blood pressure frequently.

Swelling of the legs and cardiovascular disease: pathophysiology and clinical relevance Swelling of the lower extremities, especially the legs, are a common clinical Symptom, often indicates a present cardiovascular disease. This Edema caused by an abnormal accumulation of interstitial fluid in the tissues and can be due to various disorders in the cardiovascular System. Pathophysiological Mechanisms The most important pathophysiological causes of leg swelling in cardiovascular diseases include: Congestive heart failure. In the case of systolic or diastolic heart failure, the heart loses its ability to pump efficiently, blood. This leads to an increased venous back pressure and an increased hydrostatic pressure in the venous System. The increased pressure promotes Filtration of fluid from the capillaries into the surrounding tissue, which leads to the formation of Edema. Typically, the swelling is symmetrical and occur mainly in the area of the ankles and calves. Venous Insufficiency. A dysfunction of the venous valves, or obstruction of the deep veins (e.g., thrombosis) leads to increased pressure in the veins of the lower extremities. This venous congestion causes increased Filtration of Plasma into the Interstitium and results in swelling in chronic Leg. The swelling tend to worsen during the day and reduce after a night's rest. Hypoalbuminemia in the case of heart diseases. In the case of serious cardiovascular disorders, it can lead to a deterioration of the liver function, resulting in a decreased synthesis of Albumin result. A low albumin level in the blood lowers the colloid osmotic pressure, so that the recording of fluid in the capillaries is more difficult and Edema are favored. Renin‑Angiotensin‑aldosterone‑System (RAAS) activation. In heart failure, the RAAS is activated, blood pressure and blood volume to maintain. The resulting aldosterone secretion but promotes sodium and water retention in the kidneys, which leads to a volume expansion and additional Edema. Clinical Features Leg swelling due to cardiovascular diseases have typical characteristics: Symmetric distribution (in the case of heart failure); Pressure sensitivity and possible skin changes (hyperpigmentation, Dermatitis); Deterioration after long periods of Standing or Sitting; Improvement after Elevation of the legs, or night's rest; Accompanying symptoms such as shortness of breath, fatigue, tachycardia, or orthopnea in heart failure. Diagnostic Approach The diagnosis begins with a detailed medical history and physical examination. Further diagnostic measures include: Echocardiography for the assessment of cardiac function; Doppler ultrasound of the leg veins to the exclusion of thrombosis or venous insufficiency; Laboratory tests (BNP, NT‑proBNP, electrolytes, renal and liver function tests, Albumin); X-rays of the Thorax for the assessment of pulmonary congestion in heart failure. Therapeutic Strategies The treatment depends on the underlying disease: Diuretics in the reduction of volume overload in heart failure; Compression therapy and movement in the case of venous insufficiency; Drugs for the Blockade of the RAAS (ACE‑inhibitors, AT1‑receptor blockers, aldosterone antagonists); Optimization of cardiac function by beta-blockers, Digitalis or other cardiotonic substances; Recommendations on a healthy diet with reduced salt consumption. Conclusion Swelling of the legs are an important clinical sign that may indicate a cardiovascular disease. A detailed analysis of the pathophysiological mechanisms and targeted diagnostics are necessary to determine the cause and appropriate treatment initiated. Early Intervention can improve the quality of life of the patients and the progression of the disease slow them down.
Swelling of the legs in the case of cardiovascular diseases. Diuretiko (Diuretika) ay nagpapataas ng pag-ihi ng katawan, na nagreresulta sa pagbaba ng presyon ng dugo. Simpleng paliwanag: Ang tuloy-tuloy na pag-ihi ng katawan ay nagdudulot ng pagbaba ng dami ng plasma sa dugo at sa gayon ay mas kaunting likido sa mga ugat — bumababa ang presyon sa mga pader ng ugat.

Ang presyon ng dugo ay isa sa mga pangunahing indikasyon ng kalusugan, na hindi lamang sumasalamin sa puso at sistema ng sirkulasyon, kundi pati na rin sa aktibidad ng mga bato, mga organo ng endokrin, paggawa ng dugo, at ng sistema ng nerbiyos. Kaya naman, walang isang unibersal na gamot laban sa mataas na presyon ng dugo. Hindi ka basta basta puwedeng pumunta sa botika at magtanong ng 'tableta para sa presyon,' kasi agad na tatanungin ng parmasyutiko – anong gamot ang nireseta sa iyo ng doktor? Ang mga tableta para pababain ang presyon ng dugo ay natural na nakakatulong para mabilis itong bumalik sa normal, pero inirerekomenda rin na baguhin ang pamumuhay. Ang malusog na pagkain, kontrol sa timbang, regular na ehersisyo, at pag-iwas sa paninigarilyo at alak ay magagandang paraan para maiwasan ang mataas na presyon ng dugo. Siguraduhing mas kaunting sodium (hal. asin) at mas maraming potassium (mga saging, spinach, broccoli) ang mapapasok sa katawan.
