Insights

Mortality from cerebrovascular and circulatory diseases declined in Brazil, but deaths from hypertensive diseases increased. This rise in hypertensive disease mortality may be linked to improved death certificate accuracy and rising hypertension prevalence.

Area of Science:

  • Public Health
  • Epidemiology
  • Cardiovascular Disease Research

Background:

  • Cerebrovascular and hypertensive diseases are leading global causes of death.
  • Limited data exist on long-term trends for these conditions.

Purpose of the Study:

  • To analyze temporal mortality trends for cerebrovascular and hypertensive diseases in Brazil (1980-2012).
  • To examine trends by sex and age groups.

Main Methods:

  • Utilized death and population data from DATASUS/MS (1980-2012).
  • Calculated crude and standardized annual mortality rates per 100,000 inhabitants.
  • Assessed proportional mortality for circulatory diseases (CD), cerebrovascular diseases (CBVD), and hypertensive diseases (HD).

Main Results:

  • Mortality rates increased with age for most diseases, except external causes.
  • Proportional mortality for CD, CBVD, and HD plateaued after age 60-69 (men) and 70-79 (women).
  • Standardized CD and CBVD rates declined, while HD rates showed a mild increase.

Conclusions:

  • Standardized mortality from CD and CBVD decreased.
  • An increase in HD mortality was observed, potentially due to better death certificate completion and rising hypertension prevalence.
  • Declining ill-defined causes of death (IDCD) rates may also contribute to observed HD trends.

Hypertension II: Pathophysiology

Hypertension is a chronic condition in which the blood's force against artery walls is excessively high, posing risks such as heart disease. The condition's underlying mechanisms involve complex interactions among the cardiovascular, kidney, and autonomic nervous systems.Renin-Angiotensin-Aldosterone System (RAAS): This system significantly influences blood pressure regulation. When blood pressure decreases, the kidneys secrete renin. This enzyme transforms angiotensinogen, a plasma protein,...

Factors affecting Blood pressure

Several physiological and lifestyle factors influence blood pressure (BP). Understanding these factors is crucial as they are significant in patient education and blood pressure management.

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...

Hypertension I: Introduction01:28

Hypertension I: Introduction

Hypertension is a widespread, long-term medical condition where blood pressure in the arteries remains elevated. It is characterized by systolic blood pressure readings of 130 mm Hg or above or diastolic blood pressure (DBP) readings of 80 mm Hg or higher. Unmanaged hypertension poses significant health risks, making the distinction between primary (or essential) hypertension and secondary hypertension crucial, as their management and implications vary.Primary HypertensionPrimary hypertension,...

Hypertension III: Clinical Manifestations and Diagnostic Studies

Hypertension is asymptomatic and also referred to as the "silent killer" until it progresses to a severe stage or causes target organ disease. Patients may experience symptoms stemming from the strain on blood vessels and tissues in various organs or the heart's increased workload.Physical exams might show no abnormalities other than high blood pressure. Signs of vascular damage, when present, correspond to the organs supplied by the affected vessels, leading to target organ damage. For...

Assessment of blood pressure in brachial artery(two-step method)

Measuring blood pressure is a fundamental skill in healthcare that aids in diagnosing and monitoring hypertension and other cardiovascular conditions. An aneroid sphygmomanometer, commonly used in clinical settings, offers a manual and precise method for blood pressure measurement. The technique for using this instrument involves specific steps that must be carefully executed to ensure accuracy. The following detailed description outlines a two-step technique for assessing blood pressure using...
